Ask him not to do that, revert him, get other people to help, in worst case point the arbcom at him.

This isn't really a software issue, so I'm afraid we can't do much for you here.

Well, I am relatively new in the wiki, and several editors (like a horde, about
2 or 3, who agree in that in the background) do that. They also say, that if I
revert back, I am violating the 3 revert rules pro day, But they are the
vandals, not me. Is it true, that if I revert, I violate the 3 reverts/day rule?
Therefore they can in this way eliminate my page?

They also state, that on one subject there can be only one article. They made a
voting to delete this page, but the voting showed, my page is valuable and can
be kept. However, they now state, they have the right to redirect it, without
asking me, due to the rule, that only one article can be on one subject. My
article's subject, however is "Critique" of a certain theory, and not the
certain theory. Do they have right, and can they continue like that? If not,
what are my rights, what can I do to stop their redirection?

Sorry, but this is the bug report system for the wiki software, which runs
on Wikipedia and also many other web sites.

If you're having a dispute with other editors on one of the Wikipedia sites,
you need to talk to people on that site, such as admins and perhaps the
arbitration comittee. I recommend you start with the links I posted earlier.
