Iโm not OP, but I can answer your question.
You are coming across as argumentative and rather rude about your insistence, when OP has already said whatever you want them to look into is beyond the current scope of the project, which roughly translates to โthanks, but Iโm not interested in doing that right nowโ.
And in response to that, to telling you itโs not in the current scope of a trial project, you are implying they are not doing research or learning or whatever it is (you literally said in your second comment โif you want to do a little researchโ which does indeed imply you feel they didnโt do enough). When really, you just want them to do something with their time that they donโt want to do, and frankly donโt need to do at this first stage of trial. And you seem to be getting butthurt that they arenโt interested in doing what you want them to. The condescending tone in the comment Iโm replying to is a dead giveaway.
Besides which, not everyone wants to deal with growing weed or hemp which looks identical. In fact, most people donโt want to deal with it (obtaining licenses, dealing with theft, etc.). So your focus on that specific plant through your comments seems really genuinely weird, like you canโt fathom people not being stoners or something. Thatโs quite off-putting.
If you were genuinely trying to start a conversation, you may want to look at how you approach that. When someone says they arenโt interested, like OP did, you can say โok, well if anyone else is, or if it interests you in the future, hereโs the infoโ and someone will probably reply to it if they want to talk about. You canโt just unilaterally decide what people are going to talk about and force them to participate if they donโt want to discuss it, which honestly seems like what you were trying to do.
