If you decide to do this anyways, you will usually not get audiovisual feedback from the other audience members that it was rude/​cringeworthy for you to interject, even if internally they are desperate for you to stop doing it.
You also very well might not get this feedback from the presenter. They may not be confrontational enough to call you out on it. And with the spotlight on them, they may feel uncomfortable doing things like sighing in exasperation or showing frustration in their facial expressions and body language.

There should be a moderator who does this for them.
