Its not disrespecting lore, its assuming that people wont be butthurt by something they can chose not to do. Like.. if you dont want YOUR male drow to serve Lolth... don't? Rather than insisting that someone else not be able to do it.
That's the thing, being opposed because you feel something is disrespecting a tradition is a strange position. change is scary to some. Does this really affect me, the way I play or the overall lore? Not really. Same with alignments, doesn't really affect anything current in anyway, its not saying past evil characters are suddenly not.
