There are several issues with "separating from sinners." One, we can't separate from ourselves; we are not entirely sanctified. Two, if we don't engage the culture, we will not meet the expectations of the great commission.

Whenever a person chooses sinful anger, he is, in effect, giving the other person control over him. It’s counterintuitive. In his anger, he is like a marionette, a puppet on a string.

It is not self-control, as governed by the Spirit of God, but someone out of control or under the control of another spirit. https://lifeovercoffee.com/podcast/ep-110-help-for-the-angry-person/
