How to install the latest version of Python on RHEL 8?

[snippsat]

I don't want the source code, I want to install python 3.8.1 executables for my platform (RHEL 8).

I suggests pyenv as @stranac do.
My tutorial pyenv Simple Python Version Management
Look at wiki for build tools to RHEL,it will be under CentOS/Fedora 21 and below:
A couple of site that have RHEL setup pyenv blog1, blog2

Why does IBM / Redhat hate Python?

I don't think this is true at all.

Does everyone everywhere use only Windows when using Python? Am I the only person trying to run Python on Linux?

No most use Linux here and in general the whole Python community has for a long time been aim mostly at Linux.
I use both.

Example install Python 3.8.1 on Mint 19.
This will be the same for all linux distros,after install and setup of pyenv.
