What has he done, apart from keep his sex life to himself? I'd rather not know about presenter's personal lives, and don't think they are under any obligation to tell the world about their sexuality. It seems that his wife is accepting of what happened (and it's hard to believe she had no idea after so long) so it's not for others to be outraged on her behalf either, IMO.
If he's pulled the wool over viewers' eyes in another way, I may feel differently, but as it is, he seems to be the ideal sort of presenter for a magazine show that doesn't need a Laura Keunssberg or Jeremy Paxman. I don't watch it, but just because it's not my cup of tea, not because of Schofield himself.
