Some people actually need an angry remark to know they are being an asshole, so there’s no need to say all negative activism is bad. Sometimes, it indeed does the opposite of helping, but the same can be argued for positivity. You’ll get laughed at sharing vegan recipes if the person challenging you doesn’t think animal rights even matter. But them dismissing you isn’t necessarily your fault for doing activism “the wrong way”.

That would be nice, but in a democracy, no one is going to vote to inconvenience to themselves. We have to find motivation by other means than being forced, or we will create a society where nothing good happens without being forced to.
