Distro Wars: It's All Linux
This is likely a topic covered plenty of times, and as such I won't make this a too in-depth article, but I feel it's something always worth reiterating and remembering that no matter what distribution of Linux (or GNU/Linux if you prefer) you use... it's all Linux.
You only have to whiz around the internet in message boards, YouTube comments and the like in regards to any Linux topic and you'll probably come across a "distro war" often enough. It can happen easy enough - someone mentions their distro of choice, someone else then mentions theirs and then comparisons start. From there, with personal experiences being shared, which quite frankly can differ quite a bit depending on one's hardware, software choices (or sometimes even luck) a discussion can quite quickly descend into a flame war over 'my distro is better than your distro'.
