So I have some good news and bad news for you.
The good? news is that just by reworking the game, and some tweaks to the dialogue and script respectively, the fag comment Simon used was/is already removed prior to any comments here. I can I guess somewhat agree that one wasn't necessary, and with the beforementioned comment on slight script tweak, it was already gone months ago.
I've quickly skimmed through both old script and the reworked ones (so far that's done at least) for retard, and it's used in only two cases in whole of 4 episodes. Both used by Avis, and both, imo, absolutely fine in context. One to Falazio, in a joking manner as they know each other, and one where she raged in an online game and totally lost her shit. I'm not going to put a filter on her, as in both cases I felt it was completely in character.
The post above makes it seem like it's used constantly and in degrading manner, and while I can somewhat understand, especially in the age we are, I also try to make the characters feel alive and human, and sometimes human also means using words that someone might find inappropriate. Is "moron" also not okay now? Because nothing else would fit in the context she used.
The last one however I'm truly shocked. Lame???
I've just spent time asking people, trying to find at least someone who could tell me what that could be, as I've never ever heard that or used in any such instances. Lame is an absolutely normal word, that I'm using in (copies oxford dictionary) :
"(of something intended to be entertaining) uninspiring and dull"
I'm absolutely going to continue using the word lame in future, I'm not going to shy away from using regular words just because someone somewhere uses it for slang or something else.
If anything, going on a wild chase now and googling for so long the origins of the word lame, was quite lame.
