Deliberate use of fallacy

[CapnAwesome]

Is it right to deliberately use fallacy in rhetoric if one thinks it will get a point accepted?

For example, if I know Republicans won't "get" logical arguments-- statistics on gun deaths, for example-- is it right to use appeals to emotion, appeals to authority, and argumentum ad populum? Or does this introduce a kind of Achilles heel-- you'll plow through the masses, and then end up getting embarrassed when you eventually come across a decent debater? Or, on the other hand, will you end up so wrapped up in the web of bullshit that you are spinning, that you will ending degrading your own intellect?

It occurs to me that the Fox News people, for example, may actually be highly intelligent. They may know their crowd, and may be manipulating that crowd in a measured and deliberate way.

I think 'gun deaths' is a type of logical fallacy. A death is a death regardless of the means.
