People argue for all kinds of reasons on here.
Here are some observations:
Some people argue because that is their thing, they like to stir it up and probably get great enjoyment from the responses they get.
Others like to argue with certain individuals, no matter what the topic is. They usually have some kind of cheerleading squad or support group.
Many fail to realize that most arguments (especially on these froums) are just differing opinions, often there is no clear cut right or wrong. But rather than accepting that and maybe trying to take something fromsomeone else'sperspective they try to beat their opinion intothe other persons headover and over almost like they expect the other person to say "OK your right, I completely agree with you and have changed my opinion to yours." We all know how often that happens.
I would agree with ignorance causing some but we can't forget the other one, stupidity. If a person starts out ignorant of something and then others try to inform themwith actual facts, crediblereasons, statistical support of a topic and the ignorant person still won't budge he/she has crossed into the stupity zone.
Pride and egos on a Hunting site made up of mostly men, get out of here, you guys don't know what the heck you are talking about.
