#1 I tend to agree but more so I think the true test is a fighter, fighting every style, discipline that is available and still winning not just moving up in weight. He hasn't missed weight or medically unfit since a year ago, his past few fights he's made it. Seizures is kinda a null argument as anyone can have it, but the weight cut probably did have a effect. He still performed and look amazing so I don't know.
#2. You don't have to watch him fight, I personally like watching him fight as I'm more of ground oriented fan. So I can relate in what he is doing on the ground. I can see your point but it's all different strokes for different folks.
#3. As much as I come off maybe as a Conor hater, I'm not. I actually like Conor what turned me off was the whole fake it till you make it attitude then his weirdo fans took it to the next level with spewing bullshit around. I'm more real about it in what I see from his skills alone. I agree in that he should fight someone else other than Khabib, but remember it's Conor who wanted the rematch and his fans again hammered it up. He should fight Cerrone or Al to be honest. He needs a win, bad and taking another lost to Khabib would be another nail in the coffin for the brand he has made.
I'm neutral on the religion thing, don't care much whatever works for him.
