A bit of a click-baity title I'll admit, but I didn't know how else to explain my main concern concisely!

Context/Background: My roommate (T) and I are both white transmascs (this is important for context as you will see). I'm 21 and he's 20. He is a citizen of the United States and an international student here in Australia, where I live. Shortly after the announcement of the 2025 U.S. Presidential Election results, T's Australian boyfriend told him that he didn't care who won the U.S. election, and T told me that he angrily lectured his boyfriend on why he should care, as T is a trans U.S. citizen and the election results were very dire for the trans community in the U.S. I approached T later to tell him I was hurt and offended, as he seemed to think he had the right to lecture another person on what they should believe politically, but the previous year during an Australian election concerning Indigenous Australian rights, T had repeatedly condemned me for "bringing politics into spaces it didn't belong" when I tried talking about the issues at hand. (The election was concerning whether or not Indigenous Australians should get a mandated Voice in parliament so Indigenous representatives could provide feedback on laws etc. being passed that would affect their communities. I voted in support of the mandated Voice being enshrined in parliament.)

The Situation: It quickly turned into an argument. T said the two situations were not comparable because in the U.S., trans rights were at risk of being taken away, whereas in Australia, Indigenous rights were being added. I usually avoid trying to choose who in any given situation is suffering more because of my own morals, but I crossed this line during this argument in retaliation to T trying to pick a side. As I have formally studied these issues, I brought statistics into the conversation that made it clear that Indigenous Australians AND Indigenous Americans are more at risk in multiple areas than at least white trans people are. He continued to argue that trans rights are more pressing right now, so I believe I hit below the belt and pointed out that T regularly presents himself as a cis woman to avoid harassment and acquire job opportunities, and black people can't just "present" themselves to be invisible in a system that favours white people, so from that perspective alone protections for black and Indigenous people are more pressing than those for white trans people. Later, T told me he felt that I had invalidated his experience as a trans person.

Conclusion: AITA for 1. crossing the line into the "who has it worse" competition, and 2. using T's direct experiences as a trans person to point out that he has systemic advantages over black and Indigenous people? Even though equal rights (for EVERYONE) is a very important issue to me, I feel like I got reactive, acted against my own morals and hit below the belt on both occasions.
