Can you have a go at explaining why you - and people like you - make this sort of comment?
No one argues that you do not have a right to go to the games, or to make your own mind up.
Literally, no one is arguing that at all.
So when you say "I have a right to decide", you are howling at the moon. Of course, you have a right to decide.
The argument of the majority of fans is that revenue streams should be shut down as far as can be done, and we would call on all fans to boycott.
Your case needs an argument, not that it is lawful to supply revenue, but that it is the right thing to do. Just as the argument for boycotting is not that "we have a right to boycott" - true, but irrelevant. It's that while it may well not be decisive, it's action towards the only thing that the club currently needs, which is the disappearance of Chansiri.
