FYI, the definition of sexism I'm using is the dictionary one, not "things I disagree with". I called your opinion sexist because it is sexist. Here's the definition:
1. prejudice or discrimination based on sex; especially discrimination against women.
2. behavior, conditions, or attitudes that foster stereotypes of social roles based on sex.
If you want to argue, instead of going all ad hominem and somehow trying to make it be about my supported ignorance or inability to handle disagreement, let's actually stick to the issues.
