Gibraltar should be returned to Spain

My opponent brings up the conventional and convienent argument of self determination. But one only needs to take a basic look at the events surrounding how gibralatar came to be a British colony to see how confidently self serving this actually is. This is a rare example where lip service to self determination is little more than a way to obstruct justice by a colonial occupier. 1. Where was britains respect for the rights or self determination for the original inhabitants of gibralatar? Does it not seem strange that suddenly gibalatar must remain a British possession because of self determination when Britain itself respected the same principle when it took Gibralatr in the first place? How can Britain acquire colonial possession by force without respect to human dignity but then defend its right to keep them with that same excuse? They do not have the right. Modern law is dominated by the idea of contextual law, that law needs to be interpreted to the specific context of the situation for justice to be achieved, we have exactly such a situation here. 2. To call the current inhabitants the 'people of gibralatar' is disingenuous to their actual origin. They are the colonial occupiers of gibralatar under british colonial rule. The original inhabitants were all either expelled or murdered. By calling them so Britain is sweeping its past crimes under the rug. This cannot and should not be allowed. Britain must face its colonial past and not be allowed to make up irrelevant political/legal excuses to avoid it. 3. In reality letting England get away with this would only send one message to would-be future colonizers or genociders. "Get rid of the indigenous as fast as you can and then you can claim it as yours." Is this really the message we should send? Because that is really what England has done here. Under that rational is it totally then acceptable to move anywhere you want, expell everyone and repopulate it with your own. I thought the human race was agreed in the modern age that this type of behavior is a crime. We shall not let Britain profit from it. 4. The UN have classified Gibralatr as colony that does not rule itself since 1946 to today. The British only recently made moves to get Gibralatr reclassified in light of the political pressure to return it to spain. These moves are only recently done in response to such pressure. They are not genuinely reflective of Gibralatr's true stats as a colony. In reality Gibraltar is still a colonial possession that does not truly have self determination according it the UN. This also is reality compared to British excuses to keep them as a 'non-colonial' possession in name only. 5. As detailed in comments ; there is no historical justification for taking gibalatar in the first place. Where was britains respect for the self determination of Spain when they interfered with the Spanish civil war at the time? A civil war is an entirely domestic affair and the country in question is divided and unable to negotiate or defend itself properly. Such disgraceful opportunism and complete lack of any sort if justification for the original taking of Gibraltar on behalf if Britain must have a bearing on its current determination. 6. The importance of Gibraltar to Spain goes far beyond of it to Britain; that much is obvious just from a map. But further still Gibraltar has been a key territory of successive civilizations in Spain. It was considered the dominant geographical feature since classical antiquity and has featured on Spanish coat of arms since around 14th century. Even the Spanish national motto, further beyond, is commonly accepted as a reference to go beyond the pillars of Hercules, the Ancient Greek name for gibralatar. Overall the importance and historical claim spain has on Gibralatr is self evident and non-negotiable. And clearly far above anyclaim than any Britain could have. If not for a spat of britains greedy opportunism it would never have been separated from Spain at all. 7. Self determination is not a valid excuse. Never mind that the inhabitants don't have the right to decide because they are are mere colonial occupiers, but in reality there is nothing that would change for the inhabitants that would justify it. The lives of those living in Gibraltar would be unaffected by a transfer of sovereignty. And in realty only aided by it since they rely on Spain for supply of amenities and trade. Spain the same system of autonomous self governing regions as most of Europe. What argument is there that anything changes when gibralatar becomes an autonomous Spanish territory instead of a British colonial possession besides just correcting historical injustices? The only reason the inhabitants of Gibralatr would really have to vote against joining Spain is British nationalism. Which considering the wrongs and crimes Britain committed to get Gibraltar in the first place is clearly nonsense. 8. Any defense of Gibraltar being British ultimately defends colonial behavior, defends aggressive opportunist expansion and interference in domestic civil wars, and defends expelling and massacring original inhabitants and replacing them with your own as an acceptable way to make territory 'yours' for all of time. Only those willing to defend such crimes by meaningless lipmserivce to self determination that makes no practical difference in the governing and lives of those living in gibralatar can argue that it should remain a British colony, as according to the UN.
