Nah, it's okay to post comics which contain problematic bits (and ya know, as far as problematic bits go "lame" isn't really the worst possible one); as I was saying, it's just better to put a warning for it though, so it doesn't take people unaware, and if it might be triggery for them, they might just avoid it.

So : not a big issue, just try to think about it in the future, in case you need to put a warning.
