Staying Put

Sometimes sitting there and taking it is a measure of maturity.

Getting up and walking out may register your protest, but it will do nothing to advance your own understanding, and it will almost certainly harden opposition to your viewpoint.

Maturity sometimes requires biting your tongue and opening your ears, maintaining an open posture towards things you find offensive.

Of course, if someone is advocating violence towards children or demeaning immigrants, by all means get up and walk out.
