Why does it matter here if the tax-exempt organization is religious or not? Pretty much every tax-exempt organization is going to have an agenda---if it didn't, it probably wouldn't exist. Why are religion-based agendas less tolerable here?

Religious organizations have the bonus of being able to coerce not only through threat of firing and social ostracization, but also through the threat of eternal damnation.

Tax-exempt religious organizations such as churches can (but often don't) have their tax-exempt status revoked for urging their congregation to vote for specific political candidates already.
