No like everyone on the internet I continue to argue about issues I will almost certainly never change my core beliefs about.
I mean let's all be honest here.
If you mean Internet as in broad spectrum, then yes.
If you mean DebateDotOrg (DDO), DebateIsland (DI) and Debateart.Com (DarC) then not exactly... (CreateDebate [CD] is a trollfest, it doesn't count as a proper debating website but it's ruthless banter that trains my ability to debate under pressure in ways no other site ever has)
Some do debate solely to express views they will not change, I can completely comprehend a Religions Forum main genuinely seeing DDO and DarC as much of a thoughtless cesspool of trolls as the rest of the Internet when it comes to debating. If you ventured out to any forum other than the Religion Forums and, more importantly, observed the Formal Debating, element of DDO and DarC, you'd begin to have seen a very different evolution and current status of people. These people include many of the top debaters ranked on the site. While all systems are culpable to corrupt voting screwing up the ratings system and other means to climb Elo than necessarily being the most knowledgeable and high-IQ debater, what usually is one thing you can rely on is that the people ranked at the top of the debating sites are usually the most open-minded (but not at all proportionally 1-20 is more to less or vice versa, it's dispersed but consistent with the extremes) and almost all of the people ranked on the bottom of the website were precisely there to do what you say people do on the Internet when debating. This is almost certainly true no matter how bad the website's rating system is, so long as there's genuine Formal Debating format being the means by which things are ranked and that the mods at least care enough to remove blatantly malicious, or stupid, votes.
The reason why it's almost always true that there's negative correlation between rank and how rigid one is in their views, is that the people at the top of the debate site, if it's ranked by Formal Debating and the mods at least care a little anymore to moderate ad spam and blatantly malicious votes, is that there is a secret link between the ability to debate well and the ability to change one's mind for better ideas. This is NOT as simple as 'better is more' in a directly proportional sense across a debate site's ranks but it IS very rigid if everyone were to keep at it. This includes the factor of 'debating more gets you a higher rank' because the people more enthusiastic and who would spend their spare time on a hobby as unappreciated socially and demanding intellectually and emotionally as this (trust me it's demanding emotionally if you are as dedicated as Alec or myself are to this website's ranking) then what you learn is that the people towards the top are almost always willing to consider other options and at the very least are undeniably the most likely debaters to put genuine effort into debating against their real views (or angled in between their real view and a mainstream take on it) that broaden their horizon at least in understanding why the opposition thinks what they think.
The 'flippers' who totally flip wings and severe core beliefs will always be few but you will never find that they are amongst the worst debaters unless their flips are totally random and not to do with the debates they had on the website at all, in which case there won't be that correlation.
