I agree wholeheartedly, modulo your very last sentence. I think that "yelling," as you put it, is a valid, defensible and necessary response to the yelling of the denialists, provided that one only yells things which are true. The other side has not been playing nice for quite some time, and that scientists have done themselves a disservice (along with the rest of society) by being unwilling to respond to denialist canards repeatedly and loudly. It's a tiresome and thankless job (just as the biologists), and one that I find myself poorly cut out for, but I do think it's needed.
