Tbh I think you'll find I didn't ask to get into an argument in the first place and it's quite unwelcome when some guy comes out of nowhere and tries to start one. If you think you know more on the subject than I do feel free to speak about it but if you want me to be intimidated by that when I was trying to offer my opinion and be of help, just get out. If it moves them, that leaves the obvious question. Why are there two people doing it simultaneously?
