Definition: We would like you to assess the QUALITY of each of the following argument (discussing Gay Marriage) and determine if the argument is Valid or Invalid. A valid argument is clearly interpretable and either expresses an argument, or a premise or a conclusion that can be used in an argument for the topic of gay marriage. An invalid argument is a phrase that cannot be interpreted as an argument or not on the topic of gay marriage.

Positive Example 1 -
Input: It is usually just as religiously important to same-sex couples to be married as it is for opposite-sex couples, and no one should be able to tell those people that the government cannot recognize their relationship.
Output: Valid

Positive Example 2 -
Input: We still don't have a government program of free quality childcare for working women.
Output: Invalid

Negative Example 1 -
Input: The only people who have problems with gays are the people who LET themselves have problems with gays.
Output: Invalid

Now complete the following example -
Input: a brother-sister marriage is not an extreme argument as the reasons you use should apply to those kind of marriages too if you wish to talk about it in terms of "equal protection".
Output: 


Answer: Valid
