You admit you dont engage with them - which is a perfectly reasonable choice you can make, to be clear - but without an ability to criticize the source, it's natural for them to form a community to voice their objections to your ideas, and for that community to include context. The antagonism between .ml and non-.ml users enthusiastically goes both ways (the memes you've posted here are example enough of that, as is my use of .ml as shorthand for "people that are tankies"). If you don't want to continue it, it's probably best to take the classic advice and not feed the trolls.
