The only reason to get mad at someone calling you a bad leftist is if you think it might be true. People will absolutely prey on your insecurity to make themselves feel like their chronic posting habit is praxis. The solution is to not be insecure. Be humble, do honest self-critique. Don't let lonely people work out their frustrations on you. There is a difference between pipe-lining and emotional blackmail.
You are on the path, comrade. Once you are like me, with all my irl relationships long since withered and dead, rotting even in a mass grave of liberalism, then will you know true ppbpeace. Hexbear relationships are all that remains now, for me, as they should for you. But even then I find they hang from the most tenuous of threads... ideological threads... personal threads... or the most egregious: when one is being told the reactionary lie that one needs to... to touch grass.
