Well, some of them may be working on it, so we should be positive at the start and not reject them before they even have a chance. Not everybody is bold enough or tough enough to do things right off like the hyper-intelligent folks you have listed - some people are more timid, less smart, and have to ease in - and giving a positive reception is definitely more encouraging.
Again, I know what you mean. But......it doesn't take super intelligence to vote, and it doesn't take a large amount of "guts" to do the right thing in the privacy of a voting booth.
Don't get me wrong. I welcome all "converts". But, I use the old Ronald Reagan adage of "Trust, but verify"!!
