The First Amendment states the following:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech…
To all Americans prior to the 1940’s and to most Americans today the intent is clear: the Federal government shall not give preferential treatment to any one faith and the Federal government shall not stop people from practicing their religious beliefs.
Liberals confuse the banning of preferential treatment for a particular faith tradition with the banning expression by any faith tradition. The intent of the First Amendment was to allow all faiths to be freely practiced not to restrict the practices of any particular faith.
But liberalism’s perspective is completely different when addressing the atheist faith tradition. That’s why liberals are comfortable silencing speech that is offensive to atheists, such as a military chaplain preaching the Gospel, while simultaneously supporting government funding of atheists attacks on Christianity, such as the infamous Piss Christ piece of “art”.
Some readers are probably wondering, “atheist faith tradition?” but the reality is that atheism is based on faith not on either science or facts.
