do it in an honest fashion, don't take weak potshots and run thinking you look clever. It makes you look embarassed of your own beliefs.
Which is exactly what your doing now, or do on a regular basis when someone disagrees with you. You either discount them as not knowing all the facts, or tell them there arguement is weak and they don't know enough on the topic to understand there own opinion.
Just because you can make the statement sound eloquent because of your large vocabulary ( which is impressive ) doesn't mean its any different.
