Sometimes I think the same way about hate groups (roll wih my metaphor for a sec). If no one shows up to counter protest an issue (pick one), then the event gets less press and deflates the message, which is good. It's the ignore your teasing sibling method parents have advocated for abouqt forever.
On thie flip side, this is science, often funded at the whim of officials, who make policy based on constituent expectations. That NIH funding in Bethesda could be cut because of religious belief in Texas (insert any other of your choice) means the ripple effects extend beyond geographic and demographic boundaries, and THAT's why this is a worthy issue.
Evolution might be the poster subject, but the way a people views, and funds, and ues science is the real issue with civilazation-altering consequences.
