Is this for real?

First off, and I know this will come as a shock to some, but there are fat people who are ALSO gay, bi, and trans.

Second, while there can be value in looking at how the mechanisms of oppression operate against different marginalized groups, there is no value in reductive “suffer the same” comparisons. Especially cartoonishly reductive ones like this. By insisting the oppressions are the “same”, you aren’t really trying to acknowledge fat stigma. You are trying to appropriate other stigmas and borrow that suffering.

Street harassment, bullying, etc are a part of MANY forms of oppressions, but that doesn’t make it all the “same”. Getting people to recognize ANY form of oppression is hard, but you only make it harder by making lazy analogies that do nothing but erase people’s experiences in the name of whatever point you think you are making. Don’t do it. Don’t put up with other people doing it. You are not being remotely as “deep” as you think you’re being.
