Here's my question....
A lot of people say that SL is SL and RL is RL and "ne'er the twain shall meet."
Well, in SL, my alts are different people. And the only link among them is the human behind the avatar, and that human is in RL.
So, if SL is SL, then they should think of my alts as separate individuals, and they shouldn't care if my alts have other lovers.
