Sory if it came out as a tirade, it answer on the mail before, your
thoughts in that mail, and also me complaining about some persons taking
very much freedom in how they talk to or about me, and when answered
back I am threatened to be blocked from here. It perhaps should have
been three mails instead of one, sorry if it is too diffused or
confused, it was the intention to be rude to you.

Well you can; but you didn't.

I am forced to change the mailing list while other people are not, and I
am told to "dropp of" and "watch my mouth or risk to be blocked (I
believe what he meant)" while called "for lazy idiot" becaue of bringing
up what someone found uncomfortable to talk about, and I don't see that
person being threaten the way I am; and I am not able to bring that up,
than I guess I am not welcome here.
