(1) would I be wrong in saying that if it was not for Richard Stallman we would not have our beloved Linux operating system today
First of all Linux is NOT an OS … never was … it’s an integral part of what’s become commonly called a Linux distribution.
Would Linux distributions have happened without Stallman … hard to say for sure, I gather there are/were other compilers available … but without gcc/coreutils the road to what’s “popularly” known as a Linux distribution would have probably been very different.
(2) Would I be wrong in saying that Richard Stallman is the true founder of "Linux" (the operating system) not Linus Torvalds
Erm, YES, you’d be wrong … Linux is NOT an OS but OS’s that use the Linux kernel are popularly known as Linux distributions … Stallman wrote gcc with a GNU “OS” in mind which was supposed to use the GNU HURD kernel which still doesn’t exist.
The father of the Linux kernel is Linus Torvalds … so you might be able to pick a “distribution” and say Linus and Richard are equal fathers (along with some others), but you can’t say Stallman is the father of Linux.
(3) Would I be wrong in saying that we do Richard Stallman an injustice by not always referring to "Linux" as GNU/Linux
Now this can only be an opinion, but to my way of thinking NO, the GNU toolchain is an integral part of pretty much every Linux distribution out there (certainly and AFAIK coreutils), but it could equally be argued that Xorg, ALSA, GIMP/Gnome, SAMBA, and a host of other projects deserve the same recognition, but nobody wants to call it GNU/Xorg/ALSA/GIMP/Gnome/SAMBA/Linux/etc./etc.
Or do we name it after the hundreds of thousands of contributors ?
And before someone jumps in and says none of those are necessary … try doing much with just the Linux kernel and coreutils
Nearly everyone recognises RMS’s contribution to Linux, but it had to be named fairly sensible after something … and that just turned out to be the kernel, as far as I know there was no plan for that to happen … it just happened, and is just a “popular” term for an OS with a Linux kernel … but Stallman is free to call it whatever he wants, as is everyone else … hell, call it Fred if you like 
IMHO, Linux does just fine as a blanket term that popularly encompasses all the projects that make up a Linux distribution … and it’s popular usage doesn’t detract one bit from the other projects contribution unless their input is actively denied or hidden.
(Canonical, I’m looking at you)
RMS is a genius, and modern computing would be a poorer place without him … but whilst I acknowledge his previous and continued input to Linux and FOSS as a whole, I think he’d garner more respect if he stopped stamping his feet and demanding it, and reigned in some of the more eccentric rants he goes off on from time to time 
As I said, this is just MY opinion … others are free to see things quite differently.
RMS seems to get his drive from being bitter about something … so long may he be bitter …
OK, I’ll stop doing a “Stallman” now, and this being an emotive subject, wait for someone to refute every one of my opinions
