Is it dangerous to call out a stranger if you think they’re trying to hurt you?

For example, if you suspect someone is trying to get you to a second location to do harm, and you call them out on it, will that cause them to make a hurry to do their intended harm or would it actually make them back off and pretend like they weren’t?

I ask because when the topic of ‘how would you react to..’ comes up and I say things like the above, I’m told it’s a bad idea and I should find a more subtle and safer way to escape. Also many anecdotes Ive read usually involve the person being polite and lying their way out of a bad situation.

When I say call out, I don’t mean like point a finger and be aggressively accusatory. I mean more like ‘hey man im feeling really weird about this so I’m just gonna go. You’re a total stranger to me and if I go with you I’m putting my self in danger, so see ya.’

Ive not been in this position but should I find myself there I want to be prepared.
