They [ed. guns] can be bought with a license. It is irrelevant, as a gun is a commodity whose possession is a matter of choice.
And they just wouldn't issue licenses in places like Washington DC, which caused another round of lawsuits and court cases. So how about this. We allow gay marriage, but to do so they have to get a marriage license that nobody in government will ever actually issue. That's the situation "licenses" put many gun owners in.
Discrimination against women, blacks, or homosexuals is discrimination based on what they are. That is not a matter of choice. Once again, the bigots showing their true colors. A desire to persecute others.
But Chik-Fil-A isn't discriminating. They hire gays, they serve gays. Gun owners aren't claiming that nobody should be
allowed to donate to Sarah Brady, or that those who do shouldn't be allowed to open a business, or that any person who patronizes a restaurant whose owner donated to Sarah Brady is somehow an evil hater, or that supporting organizations that support calls for more gun control
is of itself a violation of the 2nd Amendment.
