From your subject knowledge and comprehension you almost certainly do not have a postgraduate degree, I have a PhD in soft rock geology. I have explained to you twice that opportunistic means taking whatever is most readily available. Under the circumstances discussed that will be most often plant material but that selection does not imply any preference. You are the only one implying preference because you are trying to crowbar in your vegetarian agenda. I see also you have cranked up a few side accounts to upvote yourself.
It is very clear you and your best friend HylicManoeuvre are one and the same person, but like a great many things you are unable to see how obvious that is. I realise now it was not fair of me to engage in discussion with someone of your calibre so I will say nothing more.
