We in the free software movement don't think of the open source camp as an enemy; the enemy is proprietary (nonfree) software. But we want people to know we stand for freedom, so we do not accept being mislabeled as open source supporters. What we advocate is not “open source,” and what we oppose is not “closed source.” To make this clear, we avoid using those terms.

Your own citation disproves the hostility claim. To answer your question, yes I was a student associate member of the FSF. Nowhere did I learn to treat non copyleft licenses as "hostile." In fact, they are so prevalent that considering it hostile/harmful would be fruitless. They are still free licenses at the end of the day (at least the ones that dont violate the four freedoms)

Edit: actually we are hostile to some open source licenses, like the ones that prohibit commercial use to any group or individual! That's a huge no-no.
