Is it okay for a player to never roleplay? [NS]

I’ve been thinking about something I’ve seen and experine

There’s always one player who’s fully engaged during combat — sharp, tactical, focused — but when social scenes happen, they step back. Minimal dialogue. No character voice. Just short responses.

It doesn’t feel like they’re bored. It feels more like combat centric (maybe).

So I’m curious:

Do you think every player needs to actively roleplay?
Or is quiet participation just as valid?

And for DMs — do you try to pull quieter players into the spotlight, or let them exist at their comfort level?

I’m genuinely curious how different tables handle this.
