It’s not that #UFO researchers aren’t taken seriously (the legit ones) but rather that many people don’t consider this topic seriously probably due to a mix of prevalent propaganda/censorship, personal beliefs, and social peer pressure. Good UFO researchers will always try to disprove a UFO case but sometime there isn’t just a good explanation for it. Honest UFO researchers are a lot more credible than UFO debunkers which will either pick and choose the cases that can easily be debunked or come up with improbable or even absurd explanations. To take the exemple of the SpaceX video, I’m not aware of any solid debunking of it. The best I have heard is fly or bird closed to the camera but again these conclusions are made while ignoring the second trajectory that can be seen of the object passing at high speed behind the explosion.
