If a thing close to an objective truth exists, there is no reason that it would preclude freedom to reject it. Flat earthers won't exist otherwise.
The kind of thing you are falsely calling "objective truth", there have been thousands that have passed, and dozens still active that still claim to be also the same type of "objective truth". All of them contradict each other and are blatantly wrong even on really basic matters. It doesn't even try to be objective truth, any attempts to even make it so are treated by the response that one needs "Faith and Belief". Not just yours, all of them.
And even if we ignore the fact that these were sociopolitical movements primarily, even if we take that people were trying really in earnest to find truth, again its ridiculous and disproved by thousands of examples to believe men 2000 years ago could find the "final truth". Much better attempts at this goal, via the physical sciences, have been refined or disproven over the centuries, let alone what those men were doing.
Your problem is that there are thousands of similar "truths" in the past and dozens currently active in the present. Which is true? None of them are able to show theirs is true and the others are wrong.
The problem with these groups is that they are taking a really hard problem and going the opposite direction of feasible ways to begin solving it. Mathematics and the physical sciences came the closest, after much pain and effort. And these groups have as yet only been able to contradict each other and each claim to be the ultimate truth.
