You are technically correct that calling anthropomorphic animals in a game "furry" is not accurate for the usual real world definition of the term furry, since such a thing like anthropomorphic animals does not exist.
But you are mistaken in your game tagging assessment, what furry means. It means what people make it mean. And in gaming it has evolved to include anthropomorphic animals. (Oh, and the word gay actually means cheerful. But it evolved to mean male homosexuality. Curious, how meanings of words can adapt, isn't it.)
Also, as I said, complain to the players and the devs for using those tags and for making them popular. Itch is not the one to blame for. Sure, you can complain that itch does not have curated tags. We all do. But you insist they are somehow at fault for peoples taste in games or usage of tags.
I have no clue why you think I could threaten your account or where I should have done so. You are probaby mistaken me for someone else. If you speak about that other post from another person, you do not even apply the meaning of email or post correctly there.
And what's with the insinstence that the existence of link handling in your operation system is the fault of itch? A "mailto" link is a html link, just like any other link. If you click on https://itch.io/ in, for example an pdf document or your mail client, or your document viewer, your system will open your designated web browser. There are several kinds of html links, should you bother to learn about them. They start with a href. Oh look, like that one:
<a href="mailto:email@example.com">Send Email</a>
a href. Now what to do if I were your operating system? Now, of course open your designated web br... oh, that is a mail link, so open your designated mail client.
And do not confuse search for browsing tags. That is different. You have a search box to insert search terms. And there is tag box to click or type in tags. If you type apples in the search box, you will find a randomly and truncated list of results, that the search algorithm deems relevant for the search term apples. If you write in apples in the tag box, you will get a complete list of all games that were tagged by the developers with apples. The list will be sorted a little bit according to some popularity criteria, but it will include each and every item a dev tagged apples, wether apples is applicable or correct for the game - or not.
