You don’t have to endorse anything.
No but presence is read as assent. I wouldn’t join a right-leaning march if people were flying Nazi flags there either. It doesn’t matter that I don’t personally support them. By being there I effectively do.
And I’m not equating a Nazi flag to a Palestinian flag. It’s just a provocative example to highlight my point.



I don’t know what else I can say to make my view clearer. There are people in those events that I don’t want to be associated with. If they would only focus on the pride thing and keep the rest of it to themselves, then I could choose to not care about it but they don’t and thus I wish to not partake.
