Doesn’t he/she mean by “many” that it’s a big portion? Why would minorities keep being minorities when they are common ?

If I have 67 green M&Ms and 33 red M&Ms, red is both in the minority and common.

There are a great many different minority groups. It's common for someone to be in one or more. That doesn't stop them from being a minority.

ah, ok. My bad. I though by 'many' the commenter meant that most of people were minorities, which does not make much sense to me
