Rules, laws, and regulations help but change only happens what the populace redefines its understanding of "right" and "wrong." In the US for example, we have laws banning discrimination on the basis of all sorts of things such as age, race, ethnicity, etc. Also laws prohibiting "insider trading" on the stock market. But proving that a violation occurred is all but impossible or impractical.
I think it's terrific that you have the temerity to give your presentation and participate in public forums... raise awareness of how discrimination hurts real people who play valuable roles in our society. That takes courage on your part and you're to be commended.
