When I argue in real life I usually miserably fail to make a good comeback, so I rehearse the argument in my head under the shower like I would actually win it :'D
Tbh I actually never fight in the comment sections or via message, even if someone is really rude to me (yes, it happened, I even got insulted about my comics a couple of times).
It's not even cause i don't want to feed the trolls, it's that if I start arguing it gets to me, and i start thinking about it. I just ignore it and forget about it, it works really great for me ahaha. And so far it never got in the way of my creativity :3
I got better things to do with my time, like drawing more art !!
