Regardless, here are some rules you will henceforth follow:
1. Even if you do not like the once sentence reply someone made to a lengthy post, respect that it contains whatever thoughts on that issue they wished to share at that time (but only if you profess to be someone who engages in respect; otherwise you are a hypocrite).
2. A certain core courtesy shall be observed -- by whose definition, I'm not sure and do not wish to provide, because to do so would be something other than asking a question.
3. Entailed in the above two points would be the idea that a one or two line tangential rejoinder to a detailed, thought-out post reflects lack of respect for the poster. Therefore, if you do not share more at a time for reasons of agreement with the first post or no real desire to have anything explained further, babble senselessly for a number of lines to appease me personal
