I think you will know what I will say to that since you said it yourself: "the word oppression because it has become a buzzword used by entitled 20 something year old feminists with no real world experience"...
LGBTQIA+ experience oppression? Simply not true. How can you even tell if someone is LGBTQIA? Well you can have sex with them or at least try, then you can deduce at least something about their gender or sexuality? Apart from that, there is simply no way to know. How can you oppress a people that cannot be identified? In short, you can't. What we have here is the same situation as vegans, they shove their opinion down other people's throats then get mad when people don't agree.
The idea of "LGBT rights" is nonsense in the first place. What rights did an LGBT person ever not have that a cishet did? Ah yes of course in order to vote for the president you had to have sex with someone of the opposite gender and decline to have sex with someone of the same gender. And of course who can forget the American law that prevented people whose chromosomes don't match their genitalia from owning land. Who can forget the infamous institutionalised ideal that aroace are not allowed into government buildings?! Oh wait none of that ever happened... So what exactly are these "LGBT rights"? Hm, no one knows, the entire "problem" is manufactured to give LGBTQIA a sense of moral superiority, I know you have seen it before - "die cis scum" "why would you be cishet? It is boring" "if you are het kill yourself", etc. It's just a normal counterculture which parasitically latched on to the suffragette's good name (who arguably did do some good work).
The unfortunate story that has been shoved to the sidelines is that mental illness is the real bad guy here. We should be working together as a society to help people, not validate their illnesses. It is very sad that so many people are losing out on the treatment they deserve in the name of 'progress'...
