You're not suppose to specifically state it is a rhetorical question, that's not how rhetorical questions work. Just like sarcasm.
you implied that you were talking about "tumblrinas" when you were talking about feminism, "Along with SJWs and other bullstuff snowflake crap," and various other things that were in my screenshot

with implications it's pretty much in the definition that you aren't supposed to outright state what you're talking about
i inferred that you were talking about "tumblrinas" based on the context
it's how it works, tony. just like sarcasm and rhetorical questions.
