It's an bad question to ask outside the context of a relationship. It's like asking a very personal question of someone before even meeting them for a first date. 'Who the LP's are' is basically none of your business unless you are entering into some kind of relationship, even then - it may be out of bounds. Of course you have the right to not take money even in that case, but that's a different thing then knowing when to ask. All of this talk about 'tainted money' is bordering on naive - it's very subjective, moreover, if people would actually take a moment to grasp how this world operates they might find a lot of things they don't agree with. I'm not suggesting people don't make decisions about where their money comes from - that's very reasonable - rather that it's much more complicated than 'boycott Nike or Chic-Filet' populism. As far as LP's - it's definitely not a question you ask, unsolicited, over email, without an established relationship. You can try to do your own research on it, or, ask 'in person' once you have some semblance of a material conversation with an investor and hope they give you a hint one way or another. It would help to ask it in an informal, indirect manner, possibly lumped in with a few other speculative LP questions.
