Your comment said "welcome to Amiga games", as if it were unique to Amiga. The context of the thread is PC, where they had their own booter/bare-metal games.
So you don't have to go to "Amiga games world", you're already in the proper world.
And yet, your little slice of the world doesn't represent the world at whole.
If you're ignorant of the situation, maybe don't come out with such a self-centered (and arguably, arrogant) statement; and especially don't double down on it when corrected.
People also have have the choice to ignore their racist grandparents spouting right-wing ideology or try educating them out of hope they'll shift their viewpoints.
Unfortunately, like many in that group, it seems you'd rather double down on your ignorance.
