But yet, nobody has downvoted any
of your posts in this thread... I even voted up
your post reporting back the results of your "control test" (which you only done in the first place because Olivier5 had the foresight to suggest it).
Anyhow, interesting "experiment". You seem to have expected the results you say you got, although nobody can verify anything you've said since you didn't
provide any links to the posts you're referring to AFAICS. So assuming you're telling us the truth; then perhaps they didn't take your first post (about killing "white people") seriously, and I can understand why too - particularly the way you worded it. In that case, I'd say that they took down your second post (and suspended your account) not
because of "double standards", but because they thought you were/are a troll, and maybe to a lesser extent, because of the current political climate. And therefore, in that case, their decision probably had very little (if anything) to with "racism".
In any case, your execution was poor - particularly if you used the same account in both "tests". So I'm not sure your "experiment" proves much, if anything (particularly if you did
in fact use the same account for both "tests").
For the record; if I was a mod and I saw something like that, I would have immediately thought it might be some kind of sick joke/trolling/experiment, and likely would have taken the same action for the reason that the person is likely a troll or similar, and they obviously cannot contribute anything meaningful to a discussion.
(also note that I requested my facebook account be deleted some years ago now, and I haven't looked back since and don't miss it one little bit
