No, I'm very much against any form of hate, not sure what led you to imply that?
The statement "a person and day we can all do without" was hateful towards a man who put the better part of his life towards advancing ecological issues, and about a day which invites awareness about the damage people are doing to the Earth ecosystem. Both of those are objectively beneficial to humanity as a whole, and hatred towards them is sociopathic at the least.
I leave you at that, since I don't think you're arguing in good faith. Cheers.
