My name is not against ToS/Rules - Yet being forced to change it

[Solakor]

You pointed out the reason your self, the letter Z is just that, the letter Z, its origin is for language and was simply coopted by something else into a negative connotation.

While the word you are defending is the opposite, its origin is a negative connotation, how do you think people are going to interpret that?
Even if you were ignorant to the words origin, the second you learn about it any sane person would think "thats kind of weird" and most likely not even entertain the possibility of correlation and stop using it.

And words evolve. Something that was bad once does not forever only retain the bad meaning. Just because a certain group can only look at it in bad way doesn't mean it is bad and in this context it is nowhere near bad. Also the word loli does not mean the same as lolita etc now.
