Marriage discrimination struck down in Arkansas.

[Jackalope]

If the government stayed out of marriage then ssm would be legal in every state.

Effectively yes....this whole debate exists because of government meddling where it shouldn't.

Perhaps - but the reality of the situation is that in this country, marriage is very much a matter of civil law - and as long as that is the case, it is the duty of the government to ensure that all persons have equal treatment under the law.
