Bans aren't issued for single posts, and none of your posts were removed. You received three warnings, and the final one came with an indication that it is, well, final. Shortly after that warning, you doubled down, because apparently you took it as a personal challenge to do even worse.
Aside from the post you already quoted (which is an obvious off-topic rant of "aside from [the thread's topic], here are other things I dislike about FET") here are a few examples of the quality posting that earned you your warnings, and started you on the path of short bans.
A long diatribe about how great RET is, in response to a question about FET which you don't even attempt to address:
Gyroscopes, as used in aviation and other navigation applications, are pretty compelling evidence that the earth isn't flat. [...]
Either all of this stuff is part of some grand conspiracy involving every aircraft designer, and every avionics maintenance engineer (bearing in mind the kit wouldn't have worked properly if non-existent errors were being corrected), and every pilot etc, or the world is, in fact, a rotating oblate spheroid. I know which one I believe.
followed by a declaration that there
obviously isn't an answer to the question:
Indeed. Well put Ronj - thanks
There is no FET answer, is there? It doesn't exist. The earth isn't flat.
A thread in which you complain how mind-boggling it is that others might not share your position on things:
https://forum.tfes.org/index.php?topic=17466.msg227036#msg227036Arguing with a literal spambot, because checking whether you're talking to a real person is too much work when there's some "I DISAGREE!!!" to post:
https://forum.tfes.org/index.php?topic=17459.msg226838#msg226838There was, of course, the lamp post thread fiasco, in which you simply refused to address your opposition, instead declaring that no response was given to you and restating the same position
six times.
In short: if you cannot participate in debates without either just shouting "EARTH ROUND RARRRRGH!!!" or arguing in terrible faith and pretending that your arguments are the be-all-end-all of a discussion, then you shouldn't be posting in the upper fora. The fact that you chose to ignore all warnings and pushed things to the point of your second ban does not inspire much confidence, either.
