It would be impossible for me to be a lifelong liberal voter with a track record of donating to liberal causes, a certificate in LGBTQ studies and a history of activism on a variety of issues.
Sensible people can have sensible disagreements. Jumping to insulting people who disagree with you and tarring them is poor form and reflects badly on your position.
Are you insulted by comparison of argument structure? Good, perhaps that'll help you see how black people might feel when they're faced with people like you, who insist on using terms that would have never coined if black people weren't an underrepresented minority in the software industry.
