It's a hypothetical discussion. If they exist, based on the evidence we have available to us, what properties must they have. If you can't handle having a discussion about a hypothetical particle that has been neither proven to exist, nor excluded from existing, I suggest you stop interjecting in an aspect of the conversation you clearly have no interest in participating in. Otherwise you simply come accross as a troll and an ass. For someone who was recently berating someone else for speaking authoritatively on an ambiguous matter, you're certainly doing a good job of that here and now.
