The friend who tells you your idea has holes is doing more for you than ten who just say “fire.”

Agreement costs nothing, which is why it is the default setting in most group chats. Saying an idea has a problem risks the mood and risks the friendship slightly, so the only people who do it are the ones invested in the thing actually working. Most encouragement is politeness wearing a supportive face. The rarer response is somebody spending social credit on your behalf.

Take one idea to the person most likely to poke holes in it and ask for the worst three. Do not defend anything while they talk. Then thank them, because you just got free what most people pay for.
