There are people on both sides that do the same. You bring them sources, they disprove each by just looking at the link. In some cases it's justified, it others not, but usually it's a waste of time indeed. I don't think internet battles have any use. Someone comes with an argument, you present your argument, they call you dumb and disappear, then comes next one with the same argument and does the same and next one and next one - it never ends.
