Eh if they want to flip, let them. If they don't truly buy into what we buy into, don't try to change them. Most likely, their mindset and trading ways are already set in stone.
Sometimes the short term flippers actually bring randomly good DD to the board. If you disagree with them, no real sense in calling them out unless they are flat out lying or attacking somebody. In which case, I can see several others backing you. If I see somebody post it's going to .0001, I don't even bother opening the full message. Same for those claiming $5. I have my set of beliefs and justifications, and I let the stock play out. If I need to reconsider an exit, I will as new information becomes available. So far, no new information has threatened my exit point.
