Comparing 'legally blind' people to gays is called a false equivalency, which is one of many logical fallacies used by someone who either doesn't have a grasp of the issue they're discussing, or are deliberately attempting to distort it.
'Legally blind' people (such as myself, who has the worst dioptre rating two optometrists have ever encountered) do not suffer random acts of violence for being blind, or routinely get discriminated against by policy. Attempting to compare the two is as absurd as requesting that people remain politely silent while they still suffer discrimination.
It's a modern day spin on the old 'loud uppity women / Jews / Blacks would be better off keeping quiet' that conservatives use as a form of passive resistance to progression, and it has absolute zero empirical truth value. If you find yourself getting irritated over progressive activism, you should take a long, reflective look within yourself. Instead of asking, 'why do they care so much' you should be asking 'why do *you* care that *they* care so much?'
Of course, the answer is going to require honesty that may not be possible.
