Oh, another thing to consider, especially when it comes down to discussion on social issues and representation: saying it's just an opinion, people don't have to agree, doesn't shield that opinion from criticism. There are very much things as wrong opinions, usually based on misinformation or the individual's limited perspective. For large topics (I get the it's my opinion, that's your opinion routine whenever climate change comes up between my dad and I), but for topics like this as well.
If entire groups of people - minorities, women, etc - are saying that representation and such factors matter to them, affects them, has an influence on their enjoyment and on the medium, let's talk about this, let's address this, and your response is that it doesn't really matter, it's not really a problem, why do people care so much, it's just games, it's just movies...that's less opinion and more denial. Oh, it's an opinion, but it's one based in that individual's limited perspective and refusal to consider a perspective larger than one's own.
