(2) People who are for legalized marijuana are called pro-marijuana. People who are for legalized guns are called pro-gun. Pro legalized gay marriage = pro-gay. etc. etc. You get the picture.
I respect the desire to make reasonable distinctions. I make a distinction between people who are merely pro-legalized-abortion or pro-abortion (e.g. Bernie) and a person who actively, relentlessly promotes it, an abortion fanatic, extremist, or (a little bit more PC?) an abortion enthusiast (Hillary.)
I am not arguing the morality of it.
And you make my point.
One can be pro-gun rights and not own nor intend to own a gun. He/she does not even have to join the NRA or wve a sigh. He just feels that it is a right for those who wish to own one.
On the other hand one who is pro gun probably has at least one and more than likely has several.
Regardless of how the terms are used, there is a difference.
