Uninstall Pidgin
I am a member!
Is there a way to uninstall Pidgin, or will uninstalling Pidgin remove my whole desktop?

You will just uninstall Pidgin. It's safe.
sudo apt remove pidgin

There are probably many software and packages I don't use on Trisquel (among which pidgin), but I prefer not trying to uninstall them as they don't create any trouble for me and I might be creating trouble for myself by removing things I should not remove.
One that I don't use and is creating a little trouble is icedove because of its rather large and regular updates, but I prefer keeping it in case.
Of course, it is up to you. By having trisquel-recommended uninstalled, I guess the only risk is that some day, some package is added to trisquel-recommended that you uninstalled, then you won't have it installed, possibly creating some problem. This could never happen though.
I do not think that would "possibly creat[e] some problem". Without the meta-package, upgrading will not never install new software, that Trisquel's developers would have added to the default system (as a new dependency to the meta-package). That is all.
