Perhaps OP meant Pascal programmers arguing among themselves, rather than arguing with anti-Pascal programmers? I'd expect such a smallish community of developers to find plenty of common grown in such a stable technology, so no need to throw stones.
Serious question: are these languages actually controversial? Doesn't "controversy" usually mean people holding strong opinions and frequently disagreeing? I rarely hear anything at all about Pascal or Visual Basic. Maybe they were controversial in the 1990s? Now I'd call them merely unfashionable.
