You are correct about the Glock perfection fanatics, but the 1911 crowd has it's share of them too.It's not always hate...but glockbois believing the perfection thing don't help.
Personally, it's not the grip angle, it's the girth and blocky shape (double stack, yeah, yeah...)
Kind of like holding a section of fence post.
I guess I have big hands because I really like the Glock grip. In fact I put one size larger beavertail back strap on my G20.
But like I always say, choosing a handgun is like choosing good boots. One size does not fit all.
