Just said the fucking r-word in front of my mom and was met with the usual denouncment

My mom always warns me not to use this word in front of my sister/ family member who is handicapped. <br><br>I just said it again and my mom yelled at me. It's so fucking stupid that genetics determines whether or not I can swear. This is the shit I hate about women.<br><br>Also a little disclaimer that I actually fucking love my handicapped sister and I am so proud to have taken care of her for so many years when I was a child. She is my best friend and I would literally die for her.<br><br>But I hate the fact that my mom would believe that I would ever call her the r-word. It's just so fucking offensive and I can see why handicapped women hate men.<br><br>This whole thing is about my mom, not my sister.
