That one always shits me, because of course people noticed - you can't have something as blatant as "God Loves, Man Kills" and not see that there's political content in the comics.
Thing is, the complaints are that it's not being done well. The political commentary isn't weaved into the plots or a natural result of the characters - it's poorly presented, ham-fisted attacks on the writer's ideological enemies with the barest veneer of plot. It's not the characters getting switched out for replacements, which will always draw fannish ire but it usually settles down if the replacement is done well - it's replacing them with poorly-written, poorly-drawn mouthpieces who have no character other than their skin colour, sexuality or gender. With the added bonus of the character being written poorly and often as highly unlikeable, but if you don't love them, you're only disliking them because you're a bigot.
It's that Judge Dredd story where they throw out everything about the character and the background to make a thinly veiled Trump analogy - and if you have any complaints you're just a racist. Upset that they fuck up a character so they're more in line with the writer's political views? No, it is you who are wrong.
It's that insular SJW mindset that you both refer to where you can't possibly dislike something because of the quality - you have to dislike it because it comes from a trans creator, or because it's a woman in charge and you're a misogynist, or all the reasons they use to ignore people saying, "Your not as good as you think you are." Comics have always been political, sure. But those comics were written by people with talent. People who could see when an analogy works and when it doesn't work. People who could establish context and develop an arc and make you care about characters.
tl;dr: The majority of current creators aren't talented enough to do anything with the characters under their control that doesn't represent their political views in a ham-fisted, usually continuity-breaking way. They'll just never acknowledge people are angry about their lack of skill because they can't see that they're just ... not very good at what they do.
