Do people really make fun of language learners?

I have never actually tested but I'd say I got to about B1 in Russian but have barely actually used it in the real world (it was just for fun) so I'm kind of just in maintenance mode with that one so I don't forget it. But I'm now learning French as I plan to eventually do a semester abroad in France... I hear all these stories of French people mocking or laughing at Americans speaking it. I'm not really bad at pronunciation but as someone who is kinda introverted and shy already that scares me. And I've heard stories like that in the Russian learning communities too. Has anyone had an experience like that? Does it really happen or are people mostly kind towards learners? I know that's pretty broad but let's say more so in Europe as I don't want to target this post to a specific language but for me it is about French. Thanks in advance :)
