The idea of this petition is to stand up for rights of gun owners, however asking them to stand up for a woman's right to choose as well as the freedom to marry whoever you want.
Since these are all issues of freedoms, the government should take a stand on all 3 in that, leave gun rights up to individual states, or remove laws entirely, remove any law restricting a woman's right to chose, and remove any law restricting marriage equality.
This is how congress should compromise, right and left.
