I like how every generation has the same issue just rebranded:

Should inter tribal marriage be a thing?

Should be people from different classes be able to marry?

Should people from different religious sects be able to marry?

Should people from different religions be able to marry?

Should interracial marriage be a thing?

Should people of the same sex be able to marry?

And soon, we’re about to have

Should people be able to marry robots?
