When you introduce an unflattering caricature of a slave, submissively but gratefully "chopping" cotton for his "massah", as an attempt to insult my fortitude and intelligence, you are using a racial stereotype in an attempt to win an argument. Again...bad form.
If your argument has any real substance, why would you revert to a direct, personal attack in the first place? I'll tell you what...the internet is more or less anonymous. You don't know who I am. But the next time you are in the AOC, why don't you approach a black pilot at random and ask if they are voting yes or no on the TA. If they say yes, respond with... "You seem content to lower your gaze and answer, "Yes, Massah. Thank ya, Massah." I guess we should just shut up and sharpen our hoes, there's cotton to be chopped!" And then explain the intellectual depth of your chosen line of arguement.
Good luck.
