It's very unfortunate that some A/G fans are homophobic-I haven't experienced it, but I tend to interact with multishipper people in this fandom (who enjoy slash, het, femslash and gen). I'd be curious to read the post you mentionned, if the link is at all handy.

Mostly I'm just bitching about the rarity of Merlin/Arthur/Gwen fics. Threesomes solve everything!
