In Usenet, These kind of expressions are often called DoThisDoThat expressions. These should be avoided(if they target a specific individual -- but it's okay if they're mere statements or in the DocumentMode. See also GoodStyle, which is fully in DoThisDoThat style, more properly "in the imperative", but not rude nor offensive at all). It is considered quite rude and often ignites so called flamewar. There are much better and well established expressions, which are also polite and socially acceptable.

Examples.

I don't think it is. Why don't you consider/try ...
