Kid would get broken off in a heartbeat. But the reality is guys like him are all e-bark and no bite. For all the years I've been on this board and for how many people were allegedly gonna come to Vegas and set me straight, not a single one has ever shown up. He's just relishing that I'm giving him ANY attention, sooner or later it will occur to him that I basically address him less seriously than I do my own 3 year-old.
Guys like him, if they ever screw up the courage to actually show up, tend to be alarmingly reasonable in conversation and often explain that they had "personal shit" going on when they were making sideways-ass comments online. Once upon a time I used to feel sorry for them and I'd try to either talk sense into them or guide them the right way, but they systemically sabotage everything. I'm sure this is why he hasn't amounted to shit in life, or at the very least is so unhappy with what he is doing that he spends a ton of time trolling Sherdog.
Nowadays, though, I just call them out. Even in the gym. I'm willing to let them be as long as they accept what they are. That dude I mentioned who hangs around Tocco's and was shadowboxing with a blindfold on, he would go around trying to get kids to do mitts (him holding them) and giving unwarranted advice left and right. I hard-checked him on that myself when he had one of my kids in the ring, and the kid knew maybe 2 punches. Let him know trainers don't take too kindly to just telling kids to do shit they don't know how to do without even asking. Everyone knew what he was, but he swore he was gonna do this fight game. Then it came time some trainer had enough of him requesting sparring and he got put in with a former Pro MT fighter turned boxer and got absolutely tooled for 2 minutes before the gym owner stopped it and basically told him he can't ever spar again unless one of us verifies he's qualified to do so.
Spacetime literally has ZERO evidence of any credibility. He's not a complete moron so he can observe things and sound halfway smart sometimes, but as long as we just keep letting anyone he advises know that he doesn't know dick about actually doing this, then we're good. He's not even a fan of combat sports, he's a fan of the idea of being a participant in combat sports.
