see the similarities here?

1) because of reason XYZ, guns should be banned; because of reason ABC, guns should be allowed.

(because of reason XYZ, I should buy this stock.)

2) here is what I saw in a weapon factory.... so guns should be banned

 (here is what I read from an internet chat room... so I should buy this stock).

 

sounds so similar.. how about this :

3) hard facts show that liberal gun law = lower crime rate, therefore ... draw your conclusion here.

(because PRICE has done this and that, therefore I should buy this stock)

does 3) sound a little better than 1) and 2) ??
