comparing the nazis in idlib to the ira, or the situation in ireland to syria in general, is truly offensively stupid.
the situations have essentially nothing in common with each other; the ira believed in segregation, and that was wrong, but they never tried to eliminate any ethnic groups, they never set up concentration camps, they never tried to conquer the surrounding areas, etc.
it's an utterly ignorant comparison, and the people that are making it are utterly ignorant people.
