How do I express controversial ideas?
If you find the right group of people who understand you, find out where they go an what they like. You're bound to find likeminded people through them. Also, don't be afraid to go where you might not be welcome, but try to bridge the gap by taking the time to listen to people that you don't agree with so you can find some common ground. They will be more open to hear you out if they know that you at least care what they have to say.
