@foo = instance variable; each instance has one
@@foo = class variable; only one shared among all class members

class Example
def print
puts @y, @@z
end
def initialize(x)
@y = x
@@z = x
end
end
e1 = Example.new(1)
e2 = Example.new(2)
e1.print
e2.print

The first print prints 1 and 2, the second prints 2 and 2. The first
new sets e1.y to 1, and Example.z to 1. The second sets e2.y to 2,
and Example.z to 2. There's only one @@z (also called "Example.z"), but
there's one @y for each instance.

Christ said that the persecution against antizionist "goys" by the
antichrist Ersatz jews will be extreme in the end times. So I would
expect the ZOG to shut down all antizionist "goy" free speech and to
establish ZOG shyster snake laws making antizionism a felony crime
punishable by fines, imprisonment, hard labor, or death, depending on
the whims of the antichrist ZOG pig "judges" that make those sadistic
and greedy and arrogant and filthy and inhumanitarian decisions.

And Christ never lies. So you know they will. Most of us pacifist
activist antizionist "goys" will probably end up in their ZOG "FEMA"
interrogation and torture camps and prisons and jails and so forth as
ZOG POWs. The ZOG police and ZOG military love to rape, torture and
murder poor and unarmed or vastly outgunned antizionist "goys." So
they'll be following the African born puppet, invalid "president,"
zionist rubber stamp, and AIPAC/Knesset teleprompter reader Barack
Jewbama's parroted so called "orders" with great enthusiasm.

However, by silencing all "antisemitic"(tm) voices, the ZOG will
make antizionist martyrs of millions of antizionist "goys." And that
will foment so much militant opposition to the antichrist ZOG pigs,
that millions of pacifist activist antizionist "goys" will become
zealously militant and take the battle to the streets. It will be
open season on the Ersatz jews and the Ersatz zionists and anyone
that continues to support the filthy antichrist ZOG pigs.

A global nuclear and germ warfare holocaust is inevitable. And is
the goal of militant antizionist "goys." To force the filthy greedy
arrogant genocidal antichrist ZOG pigs to do the "m.a.d." thing.
Because it's the only way to solve the jewish problem once and for
all. The war that truly will end all wars. Because we antizionist
"goys" have the promise given to us by Christ that there will be a
small number of "elect goy" survivors to carry on the human race.

So bring it on! Hope that the filthy genocidal antichrist ZOG pigs
outlaw antizionism and commit mass genocide and horrible and bloody
atrocities against millions and millions and millions of antizionist
"goys" all over the world. Because at some point, with so many
millions of antizionist martyrs dead and their souls in Heaven, the
military opposition against the Ersatz jews will be so great, that
no Ersatz jew on the earth will be left alive. And everything the
Ersatz jews and Ersatz zionists and Ersatz israelis and Ersatz
christians and Ersatz moslems and all false human beings ever built
or touched will be totally destroyed.

So complete will be the ZOG's global destruction that future "goy"
generations will not even know that the jewish problem ever existed.
And all the filthy dead antichrists will be burning in the pits of
Hell for all eternity. Never to be seen nor heard from again.

Well, I have no idea what "majority of Jews" think and have no way of
knowing. Having said that, I must concur that there are those people who
will make every effort to censor Usenet. If these people have their way,
the Internet here will resemble what the Internet in China already does.
I know something of this as I'm married to a Chinese mainlander and have
a son-in-law in their army.
