I have an unpopular opinion. I believe people should be able to fly nazi and confederate flags on their private property. (Even if their private property overlooks yours.) I believe football players should be able to kneel during the national anthem.
And I believe private companies should be able to exercise their freedom of Association rights based on their beliefs or their bottom line.
All of these are just people having opinions. If you don't like their opinions, don't associate with them. That's the freedom that you have. I don't think any of this is a problem. Certainly none of it is censorship. The man flying a nazi or confederate flag in his yard alongside his JEB Stuart statue is not censoring MLK by refusing to put up an MLK statue as well.
The people who want an MLK statue should go put the MLK statue someplace else. The people tossed from Patreon should go raise money elsewhere. They're all perfectly free to do so.
