What if I genuinely don’t understand what they’re saying, and neither does anyone in my team? This happened many times. Is this racism or a practical inconvenience?

I find the sensitivity on this topic regarding racism kind of overshadowing the practical aspect of not being able to understand what the other person is saying.

We offer people in our company English language training, because we’re a world wide remote company and everyone should be able to understand each other. Is this racism as well?
