Your original post, as well as your followup, was dismissive of the Scientific Method, which includes the stipulation that all hypotheses are subject to reevaluation upon further investigation. You belittled the number of examples of instances in which feathers have been discovered in the fossil record as “a fossil or two,” which carried the implication that this was the only evidence upon which the hypothesis has been made. More basically, you confused hypothesis with theory. The proposition that birds evolved from dinosaurs is presently only a hypothesis; although its validity is supported by findings other than feathers. Your objection appears to have a political basis, rather than a scientific one.
There are more reasons than the finding of feathers that lead to the dinosaur-bird connection. The pelvis and hip structure of dinosaurs that stand on two legs, like the T-Rex, in contrast to those that walked on four legs, for example. Your objection displays a lack of knowledge of the basis for the proposition that birds evolved from dinosaurs.
