You appear to have missed my point. My second para is simply an example, not the point I'm making.

The point is: your friends don't have to be interested in exactly the same stuff as you, they just need to be interested in you.

Ah, but the parent made the explicit point of trying to find people they have two specific topics in common with. To argue that they shouldn't, doesn't help them in their quest for what they are specifically asking about.

It's ok to want to look for people with common interests, just as it's ok to feel it's enough to spend time with people you don't have a lot of common interests with.
