This is a loaded question. Racism today is based largely on perception of intention rather than action. If you're on the left, you will probably believe everyone on the right have bad intentions, and vice versa. If you don't fall into that trap, you are actually a minority.
The label of your political and religious opponents as ill-intentions goes back far into the ancient era. Wars are waged on "barbarians" because how could anyone who think differently than us be good intentioned? They must be evil people who must be wiped out, or so people thought.
What a lot of people don't understand is that it's hard to understand people who think differently than us. We believe we understand them, because we think using OUR logic and OUR experience, but we completely misunderstand.
For example, some people don't understand what's so great about video games, and believe that all people who play video games just want to act out violence or are stupid. If you don't see the point of video games, for sure video games will look stupid. Same with beliefs. You wouldn't understand when people cosplay, or when people say memes. You would think that the person is cosplaying because the person must be racist and sexist. After all, what other reason is there to cosplay besides racism and sexism? It just doesn't make sense.
Instead of believing that everyone who acts in a way different than you is ill-inteintioned, we should try to understand others with an open mind and a different perspective. Sure, you can keep your values and disagree with actions, but don't assume everyone who disagrees with you want to eat babies and kill kittens.
