Hmm. perhaps you'd like some reality:
1) Person who says they run it says "steam doesn't work on linux mint" 2) others come out and confirm that it does actually work on Mint. 3) you argue with person that makes original claim, and ignore that it actually does, in fact work. 4) When pointed out that LM does work with Steam, you reply that you don't follow the argument. 5) you then decide to expand on this false premise that something isn't working with a specific flavor of linux by comparing it to Android fragmentation, even though there isn't a case of fragmentation actually happening.
You still are unapologetic for your ad hominem, and decided to double-down on the fragmentation issue to move the goalposts.
To reiterate: Steam works on all reasonably-current flavors of Debian, Ubuntu, Redhat, Arch, Slackware, and even Gentoo.
