What you are saying is irrelevant. The discussion is about a guy trying to discredit other peoples education to promote his own. It is that simple. He does not rant, he does worse.
He should stop those practises, CDS/Capreolus have to promote their own, not try discredit other people or the level of education, because anti's will see and use this. The danger lies within, keep discussion out of the public eye.
When, not if, political views change on deer management, which is allready somewhat ongoing and will continu, (because the numbersgame is won by cities, not the country) the whole industry is in trouble.
Same happened in Holland, hunting is dissaster here now. People are more and more detached from countrylife and believe the Disneyfication in media of nature is real. This will happen more and more in the UK also, because cities grow way faster.
We have anti's now being sponsored by charity, funded by government and guided by very good lawyers. These anti's operate international, there are no information boundaries in this age, so this all will be shared. I think you very much underestimate them.
People really should stop discussion out in the open and work together. There is enough to go around for everybody. This type of YT clip by a known hunter in Holland could lead to political questions about the level of education, public safety or even lawsuits and lead to banning hunting for private people. Nothing goes unnoticed.
