1. We already know our own sexuality. We're not gay or need to experience this.
2. We're not MRAs as we stick up for the most physically unattractive peeps out there. We accept they're physically looking disadvantaged women however they don't have our unique problems. Elaborate on this.
3. We don't feel or claim to be entitled to sex. However refer them to Maslow hierarchical needs
4. Why can feminists espouse Misandry but we can't vocalize our upset?
5. Why do you think that women virtue signal about personality and being sapiosexual but in fact then admit to saying they can't date ugly guys?
6. We have a wide range of ethnicities, religions and varying political stand points. We're not ALL alt rights and white men. They make up a equal proportion of our members here.
7. Your thoughts on Elliott Rodger and Alek Minassian. AM = dodgy Facebook message which could have been generated by an artificial facebook message website. ER = he killed fellow Incels. He broke the 1st rule of the Incel commandments.
8. You can't be collectively held to account for what other Incels do. No Incel is the same. Stop them using any et tu quoque arguments on you based on this.
9. Prepare against anecdotal and apocryphal red herring cherry picked story evidence to be used against you.
10. Be prepared to explain the

and how it applies for peeps in general and is universally applicable.
Some more when I can think of it. Ps it's 5 am in England. You've got 7 hours to prepare. Good luck.
