Lefty believes there's no need for debate because they're correct on every issue. So disabling comments is just meme worlds way of telling you "you're not allowed to say that", which they are always quick to do out in the real world when they hear something they don't want to hear.
Of course they don't get the pleasure of telling you that with a smirk on their face here at imgflip which probably harshes their mellow just a bit and for that I am glad.
