> The details vary from country to country, of course, but some of the tax exemptions which religious groups get are actually just standard exemptions available to all non-profits, or all charities.
Right. Religious groups in the US get tax exemptions that non-religious 501(c)(3)s don't get. Churches can exempt themselves from FICA taxes. Churches are not required to withhold income taxes on wages paid to ministers. Churches can provide a housing allowance as compensation to ministers which is exempt from taxation

> When people advocate ending religious tax-exemptions, do they mean to end tax-exemptions specific to religious groups – but not available to charities in general, or non-profits in general? Or do they also mean to deny religious groups their status as charities? Or even their status as non-profits?
I can't speak for anyone else, but I think churches should not get special treatment relative to other charitable organizations.
