No not at all. This is about the right thing to do in this industry from a deontological perspective. I believe that engaging in wider narratives to secure the development of expertise, responsibility and risk management , is important. Please do not misunderstand my view, qualitative viewpoints are by inductive reasoning. However, differences of opinion are important in decision making. I respect your view and the rules.[/QUOTE]
You know, this statement really doesn’t make sense (and I use this kind of language in my professional life). It is also internally contradictory.
As far as the amateur/professional question, as everyone has said on numerous COTH posts, and on this one, the USEF rules on amateur and professional status only apply to what classes you can show in. The USEF does not run a larger licensing bureau for instructors, or monitor the hobby and business activities of all riders in the USA. No one does that. In other words, no one is in charge. Things might be different in other countries, but that’s how they work in the USA. The USEF distinction between amateur and professional is only about whether you show in open or adult amateur classes.
You could teach one or two kiddies walk/trot classes, and therefore have to declare yourself a professional, and compete in open, even if you really don’t have the skills or knowledge for anyone over the age of seven to think of you as a professional instructor. You could be a highly skilled amateur, able to ride and train difficult horses, a better rider (and potentially a better coach) than many pros, but if you’ve never taken money for your services, you can continue to show in AA, though you might also be winning in open.
Plus, if you go for a certain time period without taking money (I think it’s a year?) then you can reinstate your ammie status with the USEF.
In other words, RBAKA has made a basic ontological error about the nature of the USEF. Given that error, there is no deontological argument to be made here. 
As far as Marina, I don’t know her or the VA horse scene. But her bio and website suggest she must be over 60 by now, and hasn’t shown in years. She’s clearly trying to hold to the standards of her youth in Germany, which is going to interest some clients, and not others. She’s kept her own facility going for some time, apparently, but is not a household name.
I can’t see any point in worrying about her USEF status, or even bringing it up, unless you have a particular personal quarrel with her. In that case, it would be more interesting to hear about the quarrel
and we could all get popcorn. As they say on COTH
