The world says yes without carrying general conviction: 50 % think you can love two people at once, 33 % say no, 17 % decline to decide.
The gender divide is total. Men answer yes unanimously. Women do the opposite: mostly no, with a minority in favour and a share of undecided voters. Few questions in the archive separate people this cleanly.
Age traces a clear progression: the 45-54s are unanimously in favour, the 25-34s split in two, the 18-24s hesitate a great deal, and the over-65s reject the idea outright.
The thread's two contributions come from opposing camps, and yet they say almost the same thing. Both accept that you can feel something for two people, and both specify that those feelings are neither of the same nature nor of the same intensity.
The difference lies in the next step. The majority voice separates the feeling from its practice: sincerely loving two people does not make a three-way relationship desirable or workable. The opposing voice draws the reverse conclusion from the same observation: if the love is not of equal intensity, then it is not really loving two people, so the answer is no.
The disagreement is therefore not about romantic experience, on which everyone agrees, but about the definition of the verb « to love ». That probably explains the vote: each person answered a slightly different question.
