I ask for a topic and you refuse to link one... great. Generally if those that might be
But anyway I assume you mean

I am not seeing anything I would regard as toxic there, nor attacking nor off topic. Possibly a misunderstanding with language at worst. "is there a way to download" will typically be seen as a request -- as a general rule nothing is ever truly gone, especially not nowadays (some of the earlier internet days saw some things be properly lost as nobody had backups, assumed a site would remain up, or had means to regenerate things -- give me a patched ROM and I will make you a patch from it) so someone making a thread with such a title will be assumed to at best be asking for hints.
It seems that has been resolved though and written off as a failure of language (my German is less than stellar but I can see the origin of the phrasing).
On transphobia I rarely see things get out of hand. Get the odd loudmouth, however you get it the other way and the trans lobby also calls for some really outrageous stuff (sports, laws for various things, medical interventions and timings thereof, diagnosis methods, indeed whether diagnosis is even a useful term...), has awful stats (it does seem to be a pastime in such communities to share "OMG how dangerous the world is" by means of dubious stats) or assumes stuff that is very much up for debate or in need of careful explanation. To that end I am going with draw at worst.
Some claim PMs and whatnot and while I am usually inclined to ignore such things (water off a duck's back and all that) that is not good. While I can see deleted posts we can't see PMs so I will wait on evidence there.
On closing things then shuttering things right away when there is still discussion to be had, and corrections that can be issued. Whether it started off as someone of the "ew trann1es" or some wandered by at a later date to clog up the joint the issue might still merit some discussion, or explanation if it is fact banal.
As far as white nationalist politicians (do we also have to do communist ones?) I must have missed those in the last however many years. Surprising because I am usually in a lot of the would be topics there and do also read deleted posts but it is possible.
As far as banning said same. Tricky there -- if someone wants to put "I am a purple eyes is best eyes" in their signature, title or the like then I thank them for telling me they are a moron or in a cult but whether that is grounds for a ban is a different matter (sunlight is a wonderful disinfectant and sooner or later they will realise those they are discussing games, hacking and whatnot with are that which they have come to/be taught to hate and how stupid that is).
