to me thats like saying the confederate flag doesnt mean anything, or even someone that is way too far right calling themselves a nazi.
it does mean something and there is historically a negative connotation with tankies, rightfully so in my opinion. it exudes some very poor ideologies the way i see it.
you can say it has lost meaning due to many opposed to communism calling anyone that criticises capitalism tankies, but identifying yourself as such is wild.
i didnt say being a communist was bad, try rereading that or thinking for a minute. you used connotation very incorrectly i think, or at the very least not even close to what i was referencing to.
you should learn to read, and then research logical fallacies and what the terms mean that you call yourself or others.
