I think people with ridiculous views should not have an issue with being ridiculed for those views.
You're under no obligation to agree with another person point of view. But, if you're presenting your arguments in good faith, you should be prepared to listen to the person you disagree with in good faith also. If you immediately disregard what others have to say just because you think it's "too ridiculous to consider", or throw the ad hominem starter pack: bigot, nazi, far-right, trumper, etc, then you're just insulating yourself in a bubble in the best case scenario, or showing you don't have the capability to articulate your argument effectively in the worst case scenario.
It really feels like you're the immature bunch, trying to hide who you are because you're too fragile to own up to it if it's being scrutinized.
It's not a matter of trying to hide anything for the sake of it. It's just that some people use the free availability of a user's previous posts/likes as a shortcut for "whataboutisms". You may disagree with other posts I made, but what is being discussed here is the reasonableness of individual "likes" being public or not.
I think the crude scrutiny of a persons past posts to be, in many cases, dishonored. The person being scrutinized may have changed their views since then, specially when the post is years-old.
