We have already discussed many times about Dark Matter, Dark Energy, Parallel Universes, multiple dimensions, String theory and so on...all of which are speculative but are nevertheless taken as valid scientific hypotheses. No reason why the ideas of Sheldrake should not be taken similarly.
In principal you are absolutely correct, the fact that they are Sheldrake's ideas rather than someone else's isn't sufficient basis to reject them. However, these comparisons you are trying to make are not like for like.
Dark Matter and Dark Energy are explicitly terms for phenomena we observe for which we currently don't have a good explanation - they are not claims, they are place-holders for areas where we currently know we don't have any good ideas.
Parallel universes and multiple dimensions are more philosophy than science, an idea which in the future may or may not be testable but currently is not - currently it's just fanciful thinking that borrows from some current science as a basis.
String theory is a mathematical model which explains some (but not all) observable effects at a quantum level, and is theoretically testable if a) it gets refined into a complete explanation and b) we develop suitable equipment.
Genomorphic theory was Sheldrake's attempt to explain phenomena that either didn't exist, or which had other explanations in line with demonstrated science.
His discussion is largely about Consciousness and the mind, about which science has no definitive ideas at all.
Science has not finished exploring consciousness, it's true, but Sheldrake's ideas around consciousness are not science because they aren't testable. Again, that doesn't, of itself, make them wrong, but it does make his claims of science in regard of his work on consciousness wrong, and it makes his prominent expression of his science education and background in support of his claims at least unethical, if not downright dishonest.
Also, there are many others who share similar ideas....Chalmers, Tononi, Hoffman and others. Just because Sheldrake quotes extensively from Hindu philosophical ideas, his ideas need not be dismissed as pseudoscience. Sam Harris also quotes from Buddhist ideas.
Again, it's not about who is making the argument, it's about how the argument stacks up. Sheldrake, and others, make up untestable and unevidenced explanations to 'explain' phenomena, which they're allowed to do, and we're allowed to dismiss. To my knowledge, the other people you've cited don't claim 'science' when they do it, but Sheldrake does.
