Agreed. Thankfully I was grew tall and quite strong early in life. My dad made me do martials arts as well to help, it also helped having an identical twin, although he does not stutter. I have had to defend myself due to attempted bullying a fair few times. You should never use violence if you help it but you should always be capable of it, if needed. Now as an adult, remember, I just call people out, if they take the piss at work or at a party or somthing, most people are cowards, and see us as weak, they tend to back track when you stand up for yourself.
