Of course, but the very title of the thread is a question, an invitation for opinion.
Coming in here and posting an opinion is very different to coming in shouting about everyone who doesn't see things their way being "wrong", "evil", "sinners" and all but demanding that their way be the only way. There's a little thing called civilized debate.
I noticed that everyone here who was of the opinion that living together before marriage can have it's acceptable purposes and situations said just that. The traditionalists are always the ones passing judgement, and outright insulting people who think differently.
