2 - Conservative boards tend to be filled with(to be blunt) less intelligent people(thats a compliment), but they are more engaging and reasonable. Liberals are more likely to consider anyone who disagrees an idiot or troll, and ignore them or bash them. Conservatives invite desent liberals wonder why you are here, and want you to go away
Conservatives are more likely to take the "why do you think that", or "thats not true because ...." approach.
In debating issues though, fiscally liberals allow emotion to trump logic, while socially conservatives allow faith to trump logic.(these are not absolutes). Emotion and faith, both i have found are pointless to attack with logic since they are bound by the same rules, such as the need to make sense or be proven.
