No it doesn't. Real it ALL
An establishment of religion is a church,synagogue. In otherwords, the government will not interfere with the inner workings of the church. The government runs the country, the church runs the church. That is the definition of separation of church and state, which was connonized by the church way back in 1243 or thereabouts.
The rest, "free exercise thereof" and onward, seems clear to me.
I have. That's all it says anywhere that comes anywhere close to saying that religion should be suppressed.
