All depends how it is carried out. To do so with civilised debate is acceptable whereas to go down the channel of forcing ones belief on others is not. We have to remember that the point of debate is to convert someone to your line of thinking weather that be religion, gun laws, war in iraq or even which SCI-FI show is the best. Religion always seems to bring up this controversy anywhere it is debated. As far as I see things are going down the route of a civilised debate (for the most part) where all views ate taken and debated without getting onto the realm of forceful convention.
