Re: not exactly

Even in the support forum, anyone who says they're a Christian can post, so nobody even can say who decides what a Christian is.

So, should we leave it up to you to decide who is Christian enough to post. By what rights do you decide who is a Christian and who isn't - it is the position of a self-righteous, self-important fanatic. Who decides who is a Christian? If you believe yourself a Christian then you are one. You are a Christian; a bad one in your case, and intolerant one, a hateful one, a deceitful one, but still a Christian.

But there is no "my" Christianity or "your" Christianity, only God's Christianity.

Unfortunately God left rather vague instructions, which is why we have over 3000 major sects and another 8-14 thousand minor ones.

We expect to be shot at by unbelievers, but when "christians" [sic] stab you in the back for not being tolerant enough, that's not Christianity.

Wrong, it is the very essence of Christianity.  To oppose those who preach hate, intolerance, that is to be a Christian.  

I stuck my neck out repeatedly in defense of the gospel and countering false teachings, only to be repeatedly stabbed in the back by people who had decided that Christianity means never saying anything harsh or negative.

When cops turn a blind eye to the crimes of their fellow cops we are outraged. They are no longer being cops but are now criminals. When Christians stay silent and do not oppose intolerant, extremists views like yours they are not being Christian. It is the duty of all people to oppose the extremist, hate fueled ideas you sponsor.

So, #1211, get off your high horse and read the Bible.
What she really means is 'Read the Bible the way I read the Bible.'
