We are talking about rating games here, and not about how justified someone is in their dislike. Ai is legal. In some countries lgbt is not legal. People from those countries can justify that they are more justfied to dislike lgbt, than you can justifiy disliking ai. But why you dislike something or if you are in any way justified to dislike something, is not relevant in this discussion.
Try to justify it here anyway, and you are offtopic. Go to other threads where you can discuss your views on pixel art and other things.
If you systematically downrate games, because you dislike an aspect of those games, you are abusing the rating system and it borders harassment. And of course, it would be "bad faith" to just list up a tag you dislike and downrate all those games.
If you merely downrate games you played, based on your preferences - including dislike towards lgbt topics, ai usage, usage of low resolution graphics, or because the developer uses the "wrong" social platforms - that would be ok.
But regular people would just remove points from the 5 score for their dislike triggers and not go out of their way to evaluate games that feature their personal no-deal triggers.
