In that case.. getting your share of time spent with it ending up in fits of conniption isn't a good way to either, except you would prefer to gain that extra strand of white hair or something.
Unless you state in the original topic, "Greetings, I don't want so and so to reply to this topic, but the rest of you, what do you think about _____?" you will get replies from anybody willing to share their two cents just as much as you do to freely use their time for sharing their opinions and comments.
When you are on the internet, this is pretty much what it is. There is no respect, etiquette, or rules you must follow outside of general forum guidelines and such.
This forum is already fairly respectful in the aspect of giving opinions, if you have not seen worse.
I'm sorry to convey it in this manner, but that is just what it is.
Humans live in a society where we exist to correct, or prove something to others.
