Not necessarily. And I don't think you meant it like this could be read.
You can absolutely be pro something but recognize the downsides of it. You can be pro vaxxination, but be critical of how the government handles rollout, you can be pro EV but still remain convinced that the resources needed for batteries are (at the moment) produced using child labor and causing environmental destruction. Constructive critique is valid and necessary.
People don't need to be fanboys, sitting on the fence is completely okay in regards to many topics.
What I think you meant to criticise (please correct me if I'm wrong) is that lots of invalid critique and unreasonable opposition hides behind a thin veneer of "I'm actually in favor of {x}" and yes, we're all sick of it.
