I have heard from several fellow HackerNews readers (in other forums) that Godwins Law doesn't apply anymore mainly because of their opposition to Trump, and their own or their allies behaviour in breaking this law. It seems to imply that because we live in the current year, the present day, that previous laws no longer have validity, because of the false assumption that the present day has more importance than any other time, ever. (This assumption ignores history, tellingly). That, and they consider that in Trumps case the comparisons can actually have validity.
The other reasoning given from our fellow peers that I have heard sounds like that this law was made during the era of quiet bulletin boards, made up of people with a shared mind set, with a shared sense of humour, and the Internet now has changed beyond recognition. Therefore any laws made about the internet back then have no validity.
I would like to suggest that when you consider something no longer valid it could give you pause to think about your reasonings for doing so.
