Discrediting my argument by labeling it as ideology and by implying that "blanket statements are always bad" is a logical fallacy that does not touch the merits

Discrediting my argument by labeling it as ideology and by implying that "blanket statements are always bad" is a logical fallacy that does not touch the merits of what is discussed and I would argue that your argument instead of mine is the one that does not belong here. If you want to contribute to the discussion, I'd be happy to be given an example of successful usage of global variables that made a project a long term success under changing requirements compared to the alternatives.
