It's quite natural to disagree on many subjects. In person, there is an unspoken rule to establish some level of trust and comfort before discussing contentious subjects. Some go so far as to suggest avoid discussing religion and politics altogether. Online, the unspoken rule isn't present and as a result, people sometimes simply state what they think and how they feel without the natural consideration for the person they're interacting with. There's limited information to establish common ground and hence remaining neutral, constructive and polite can be difficult. The part that I enjoy is the freedom to make mistakes - especially when it comes to taboo subjects. You can mold your stance through discussion without the worry of reputation damage that always lingers in real life. One can easily squander this privilege in favor of using the internet as a place to release emotional frustration anonymously (twitter for a lot of people) and it's good to be able to identify if that's someone's main drive, to avoid trying to reason with them altogether. In short - being aware of the difficulty introduced by the communication medium can go a long way towards re-calibrating your expectations of yourself and others.
