Flipping someone off who just blatantly insulted you without saying a word is not a tantrum. You are completely making this out to be something it's not, and it's more than a little dishonest.
She was rude, but she was explaining that she dosent view the trans person as "not a female." Her definition of female might be a strict one, ovaries, womb, has a period, but that is her view on what makes a female a female. Basically, she views the tranny as someone who is fetishing drag. I'm not saying she's right, but that is the claim she made, and flipping someone off is not the best response to the situation.
I mean, could use this Plebs argument as evidence that she is right? There is no research or logic in the trans person response, so the rude feminist comes off as right, and the tranny comes off as someone who is aware that she is wrong, but dosent want to admit it. I'll admit that this is my interpertation, but can you blame me? The trans person brings NOTHING to the table to the argument, in a political cartoon.
