Bullshit.
And just, “Reacher.”
Mr. Reacher, you realize you are engaging in an an unsupported assertion (and possibly an insult). If someone responds to the identification of their argument as “an ad hominem” by simply saying “That’s bullshit,” they haven't actually addressed whether the argument is ad hominem. Calling my characterization ‘bullshit’ doesn’t show that it’s incorrect. What part of the argument do you think I’ve mischaracterized, and why?
Your comment is itself just a dismissal unless it is accompanied by a reason or counterargument.
