I find special privileges for"organized" religions to be discriminatory to smaller religions (often referred to dismissively as "cults") or those who hold beliefs that do not fall under any group category.

Unlike protections for skin color, disabilities , sexual orientation, gender or age, religion is the only one that is voluntary.

In my opinion, it is a relic of a time when there were no democratic  means which which to organize/control/govern societies and at that time it probably served a useful function.

However, now that we have civil laws to  govern our behaviors and citizenship to give us a sense of identity, religion has no place having special privileges.
