I'm not as absolute about this as a lot of you. Cowfolds example isn't great but I'll give you some others :
1. Chanting about Billy Sharps dead baby
2. Wishing cancer on Granit Xhaka's kids
3. Chanting about Lewis Dunk being a rapist.
4. Calling someone a (insert colour, insert expletive here)
We have rightly as a society cut down on 4. Why is 1-3 seemingly tolerated? 2 and 3 have happened this season.
This is not the question that the OP asked. What is Cowfolds example an example of? Most of us think it is an example of a rediculous either/or scenario.
All of your list examples are obviously wrong. But your question is not what is best or acceptable (none of it is) but what is legal. The OP did not ask us whether swearing or racism is illegal, he asked whether one was more acceptable than the other. The answer is 'yes'. The answer to your question (if you have one) is 'no', no, none of these are acceptable.
