Everyone is entitled to an opinion, but when your opinion is expressed in a manner that oppresses another person's rights, you have gone too far. I am a major supporter of the First Amendment guarantee of freedom of speech, but I cannot support that right when that speech is intended to hurt people. As a child, I learned that if you abuse a privilege, it can be taken away. This is true with the freedom of speech. If we misuse what we have, we face consequences.
Freedom of speech is meant to allow people to say what they think without fear of persecution.
When we use this freedom to slander others or make hurtful statements, we are misusing our freedom. There is too much hate and unhappiness in the world as it is. We don't need any more. The chalkings show the ignorance of the people who wrote them. We are in a place of diversity, and no one is forced to be here.
