No. But why start them at all? It leaves a bad reputation for those franchises, IMO.
I mean I could go right now and find countless sites showing how people dislike certain companies or just certain characters.
Heck, DA--deviantART, that is--is crawling with people with stick up their baloobius' in regards to others' ways of thinking.
People outright draw incestral porn, draw kill art, and draw straight characters as gay or lesbo (not that there's anything wrong with being that way, but when a character is created in a certain way, I just like things to stay true to that character, including sexual orientation).
What worse is when official companies start doing it--such as Archie making a false Sonic (Scourge) and having him hit on & probably even do some other "things" to every freakin' female in the comics (thus, making Sonic himself appear to be something of a pimp, like that of
WWE's Godfather)--for it really burns me up inside!
