What is/is there a name for the fallacy of social progress infinitely improving?

Ignoring the claim that gays are not treated poorly anymore, it is the case that their treatment (as a group, at least here in the USA) is better now than it was in the past. In fact, the thesis of social progress (again, at least here in the USA) is a solid one for most minorities. What this doesn't mean (necessitate) is that every minority will follow the same pattern of progress. This is the fallacy of division .

The other problem is with the "don't worry about it" attitude. It is precisely us "worrying" about it causes the social change. This part is more of a problem with specialized knowledge (sociology) or perhaps cause and effect then with fallacious reasoning.

Yup. Grade on a curve. Like most white people do --Unless your're Irish, Russian, Jewish or German. They know the reasons why.

P1: Homosexuals are no longer treated badly.
P2: Homosexuals are an oppressed minority group.
C: No oppressed minority group will end up being treated badly.

Such an argument is an example for hasty generalization and illicit minor .

P1: Some minority group is treated badly.

P2: Society is constantly moving forward.

C: No minority group will end up being treated badly.

I would define this as non sequitur .

In addition to this, if your objection demands a change in the unjust policy towards the minority immediately, and someone answers that somewhere in the future things will fall into place, it is about avoiding the issue .

Final note: I have tried to cover the fallacies present in this reasoning, but it is possible that there is a contextual name for this fallacy that is not known to me and that you are looking for.
