1. Does MINORITY representation affect your buying habits?
No. Entertaining stories with characters I like drive my buying habits. I'm not reading comics for a vicarious power fantasy based on minority identification.
2. Is your MINORITY well represented in Marvel comics?
LOL! I'm neither represented well in numbers or portrayal -- I can only think of one character off the top of my head, and her portrayal has been a bit cliched to say the least, and non-existent for most of the last 40 years.
I'll leave you to the usual complaining about the plight of the only "minority" that "counts" on CBR.
