If someone started legally filming you in public, are you ok with it or unhappy with it?

People will often defend their own right to film people in public places as a legal right because there is no expectation of privacy in public... but is it a decent way to be treated?

I have not personally gotten into any problems with someone filming me or my kid, but I have witnessed people take out their phones to film an interaction between them and someone they are approaching. I can’t help but think that the added sense of entitlement to film often escalated situations that could have been worked out with simple conversation.

So if someone approached you (even calmly and non-threateningly) while obvious about the fact that they were filming, would you be ok with it and see it as their right as long as their speech and other actions were civil, or would you take the act of filming as rudeness or a sign of aggression even when knowing it is legal to do so?
