That was quite unnecessary.

I look for signs in posts of where the user is at and he said "I don't normally make bold claims but I think I'll stick with this one and maybe in 5-10 years I can fish out this blog post to see if I'm right or not" which is exactly the kind of thing that suggests a level of maturity (which = a willingness to be wrong and change one's mind and learn from experience) in the poster.

That is wildly unkind though.

Noting that the evidence is insufficient basis for the claim is not unkind.

But saying “I don’t want to be wildly unkind” implies that there is something about the author and their claim that is deserving of meanness. I think that is an unkind thing to say.

That’s a fair point. I thought the context of “unkind” was already clear from the grandparent comment:
