Trans men are men, trans women are women; this is like, scientifically verifiable. Also, there is no "straight pride" because straight ppl are not marginalised. This is honestly just something overly privileged people ask for when they feel exclusion for the first time. "Equal rights" does not exclusively refer to legal rights, nor does it exclusively refer to the West.
Also, if you'd like to buy rainbow products, pls do not buy them from "rainbow capitalists" (Putting a rainbow on a sandwich wrapper with 0% of proceeds going to charity helps nobody, and your money is possibly going towards anti-LGBT political parties)
