Who are the moral phages? These are people who blame others for immorality. That is, they are moralists who impose their “correct” opinion on other people. The very concept of “moral phage” originated on the Internet when imageboard resources (such as “dvatch”) gained popularity.
Definition
What does “moral phage” mean? This is a fanatical irrational dogma that does not share the concept of human rights and freedom. At the very least, such a definition is published on “image collections”.
Who are the "moral phages"? Why don't they like them?
The word "moral phage" is usually referred to as Internet slang. This expression originated in the West (on the same "image boards"), and was simply popularized by the post-Soviet public. There are many humorous resources on the Internet where censorship and moral values are completely absent. All content does not go through filtering, and so you can often find so-called shock content there. The ideology of such resources, as a rule, is that all users should be anonymous. There is also an unwritten rule - “the user to one degree or another knows what kind of content can be here”. Therefore, in such places, “moral phages” are not welcomed, and indeed do not like. After all, there is absolutely no sense in their moralizing and indignation towards the other inhabitants of this or that forum. The question begs: “why did you come here if you know that you will complain?” For this reason, such resources are created so that interested people can communicate with each other and share information (usually informal), and when someone interferes with them, an appropriate reaction is born.

Identification
If you are interested in the question of who are the moral phages, then know that the favorite topics for discussion of these “Internet inhabitants” are: problems of sexual minorities, the prohibition of abortion and surrogate motherhood, the practice of euthanasia, insulting the feelings of believers, the prohibition of pornography and much more. As you may have noticed, the themes are already resonant. “Moralists” just like to argue and hold opposition opinion about all this.
And in conclusion about who these moral phages are, we can say: these people believe that their subjective “morality” coincides with the universal. In practice, the moral rights of people diverge in many ways, because all people are partly different. Of course, some general norms exist, but not everyone will argue in the event of a minor discrepancy or disagreement. And the “moral phage” will fight to the last, especially if this whole story happens on the Internet.
