Fedora is giving me some grief. Whenever I modify a user's group, like
adding them to a new group, they are removed from the previous group
they were in. The syntax I'm using is: usermod -G "group name" "user
name", any thoughts?
I do not want to edit the text file directly.

(debian here)

Do you have adduser?

adduser [options] user group # I've never needed any options.

Usermod is installed on my box but I've never used it.

The -G option takes a list of /all/ supplemental groups the user is to
belong to. If you only name /one/ group to usermod -G, then the user is
taken out of all supplemntal groups, and placed in the /one/
supplemental group you name.

If you want a user to remain in all their existing supplemental groups,
and /add/ another group to that list, you'll have to
usermod -G group,group,group,new_group
or edit /etc/group directly
