Muscle is an emotional issue. By building muscle you are literally trying to create more of your self. Consequently people tend to get very emotional about how they achieve their muscle, there's a kind of religious zealotry around certain schools of training and nutrition and people will take offence if you disagree with their pet methods.
This is an unhealthy way to live. Not only is it pretty miserable, it guarantees you're not thinking logically and critically about you're training. It forces you into dumb choices and makes you anxious and insecure.
As much as the fitness industry is obsessed with "passion", I really feel we should learn to be dispassionate about our bodies. Ultimately, if you're not an athlete and just want to look good, training is basically a fashion decision. You are deciding to look a certain way because you think it's attractive or will make you feel good. That's no different to buying a pair of shoes, it just takes longer.
Some may disagree with what style of shoe looks best, but you're not going to call them an asshole for disagreeing with your choice.
Take the emotion out of the choices you're making, pick a sensible plan you can actually follow and enjoy, and then get on with your life.
