"Freedom of religion" means something quite specific to conservative Catholics. The Democratic Party views religion in terms of non-discrimination. That is, no one should be discriminated against because of their religious beliefs. In addition, the Party notes:

<<We are horrified by ISIS’ genocide and sexual enslavement of Christians and Yezidis and crimes against humanity against Muslims and others in the Middle East. We will do everything we can to protect religious minorities and the fundamental right of freedom of religion.>>

I doubt "a majority of Americans" would disagree.
