This is old territory that gets tiresome but the left persists, which is why you are posting it on this thread debunking the left’s claims about Syphilis.
No, I am pointing out that the Native Americans didn't know much about infections in general, and syphilis in particular because they were immune to that disease. So, they couldn't have spread the disease to us intentionally. We, on the other hand, were having trouble with smallpox at the time and knew it was spread by contact and clothing. We deliberately spread it to the Indians.
I think an honest and complete telling of history is important in order to learn some humility and to avoid immoral practices in the future.
You are free to believe that we have a squeaky-clean history at your own peril.
Your "leftist" label caries the exact merit as other people's "racist" labels. These are used to cover up the total inability to handle opposing views while being unable to support your own through rational discourse.
Oh, by the way, are you a photography nut? I regret giving my darkroom away from time to time; but, Photoshop sure is easier.
