That's the second time in a week or two I have seen this. Unless I'm misinterpreting the sentiment, in which case please accept my apology, it's pretty awful that there's such animosity on here that folk are wanting a square go. Can we all not just try to get along, or at least use the ignore function?
I'm 6' tall, reasonably fit and have trained in boxing and martial arts for several years and there's no way I would even consider meeting someone from an internet forum for a straightener. Firstly, even assuming you did know the other poster's capability, you don't know they would be coming alone or what they might be carrying. Then, even if you 'win' and batter the other individual you may face criminal charges and all that comes with it (loss of job, etc). It's not like there isn't a written (internet) record of evidence. For what, because some guy's insulted you on here? Really? That is a playground mentality. Violence should always be a last resort, reserved for defence of oneself, loved ones or protecting the weak and vulnerable. We're all adults here.
Think about this, gentleman.
