Him going to GAC was a bit of a surprise to me. It's true that people are clear about why they left. Candace Cameron Bure especially. GAC itself is basically a bunch of people running away from Hallmark embracing diversity. Embracing families that aren't 20-30 something white people, with or without kids, "falling in love" within a week or so. With that CEO gone they've been doing so much more than they used to. Gay couples, different races, interracial couples, non-Christian beliefs (I think there's been at least 2 Hannukah movies in the past 2 years), embracing different cultures, etc. Candace fled because of the gay couples and most likely the non-Christian beliefs as well. Sad to say it wouldn't surprise me if the racial diversity bothered her too. She seems to want the world to reflect what she sees in the mirror. GAC is a shelter from the ones who can't handle the fact diverse families are real families.
I fully expected Trevor to stick with Hallmark with all that going on. I really don't the impression he buys into all that bullshit, so I can't help but wonder why he would leave the network that had to offer more opportunities for him.
