I know that sometimes I will attack others.. but my own rendition of those situations is that in my head I have concluded that they have attacked first, and maybe I had already given them sufficient chances on the discussion of the substance (or we have a prior relation)..  Anyhow I believe that I mostly will only attack after I feel that I have been attacked first and after a certain amount of attempts at addressing the topic..but I do understand and appreciate that there are some arguments and discussion topics that are not real and genuine talking points.. so in that regard sometimes there might be some instances in which I had determined that a pre-emptive attack might come in useful, even though I do not consider myself to have such a habit,.... at least not regularly.. but I could see how sometimes preemptive attack can be useful...  sometimes. perhaps?..
