The point of first article is that LGBT people experience actual oppression and we're still nowhere near ending it, so straight people using the same word and acting as if they're experiencing the same treatment is derailing from actual issues LGBT has.
For one it's not the same word and second did you know what Phobia is ? Seem like you just quote and didn't read what i've said. Yes they don't have the same oppression but that's not the same thing we talking about. The problem lie in the fact that the article used the same base as "LGBT are oppresed" and apply it blindly to Straight.Here we talking about hating anything or anyone straight just because it's straight, that is heterophobia.
