I guess I’m in the minority, but I don’t see this having anything to do with the killing off bi or gay characters. I’m bi, my daughter and best friend are gay - I’m not insensitive to the issues for LGBTQ characters on TV. But I also don’t think you should not kill a character because they fall into that group.
I thought the whole Quentin’s death and funeral was very compelling TV. It really made me feel, and I’m kind of a cynic sometimes. But as much as I loved those scenes for the emotional impact, I do think it was an enormous mistake to kill him off.
