No it doesn't. If you're the group with the power (in this case straight cis people have the power because they have no fear of being harassed or assaulted when in public with their partner, whereas non-straight couples typically are not able to show affection in public to say the least and trans people basically struggle with anything in public) then you need no special recognition. LGBTQ people are searching for acceptance and equality and this is one way that they can show they are fighting and for people to show their support.
Almost any political issue is nuanced, but for me, if you don't support LGBTQ rights you are wrong, period. Like, this shouldn't even be a political issue. Mind your own business and don't worry about who people love or how people choose to express themselves. Go enjoy life some, and then go work to fix some real issues.
Anyway, thanks for letting me vent. This has actually been on my mind quite a bit recently. Weird place to let it out I have to say...
[I'm not in the LGBTQ community so please do tell me if I'm wrong or need to fix any nuance.]
