I got called Karen for standing up for someone?!

I got called a Karen today because I was trying to help someone see that their husband had no right to be angry at her for getting pregnant because he was just as responsible and they both knew the risks.

And some Karen called me Karen.

Her reasoning being that these people already had kids so he doesn't have to want more kids.

But I never said he had to want more kids I just said he needed to understand that he had an equal role in the conception of their baby and he is just has responsible so there was no need to blame the woman.

Am I wrong?
