LGBTQIA are getting a lot more screen time because a small group of powerful people decided we're a good scapegoat to distract everyone else (including you) from the real reason the issues you so vehemently abhor are even happening in the first place. Maybe you should direct your ire at them, it's a hell of a lot more constructive.
Also what's this about "you people"? I'm not American. In fact I come from a former colony of a European country that's still getting royally fucked over decades after independence, and the majority of the population lives in abject poverty. Don't lecture me about who's getting enough attention. Most of the people in your country have barely even heard of the place I'm from, let alone give even an iota of a shit about the plight of the people there. And you don't hear me ranting that native americans are getting more "attention" and "resources" compared to my people who are dying of rampant AIDs, violent conflict, and fucking disease and starvation. We all deserve equality and justice - focus your efforts on tearing down the causes, not other groups fighting for themselves against the same fucking oppressors.
And how is this the fault of the LGBT community? Are the LGBT community specifically responsible for native americans not getting enough attention? You have yet to make an argument why the LGBT community itself deserves your ire. Have they somehow -tricked- people into getting more attention? I really struggle to understand why you've picked on this group in particular. Are black people being given too much attention too? Women? Elderly people with dementia?
