Buddha's teaching is meant to be applied to oneself, not to measure others.
Buddha's definition of Right Speech is:
And what is right speech? Abstaining from lying, from divisive speech, from abusive speech, & from idle chatter: This is called right speech.
So the question you should ask yourself is, are the questions you ask fall into any of these categories: especially into divisive or abusive speech. Divisive speech is anything that for whatever reason -- objective or subjective -- provokes emotionally charged debates and confrontation:
Abandoning divisive speech he abstains from divisive speech. What he has heard here he does not tell there to break those people apart from these people here. What he has heard there he does not tell here to break these people apart from those people there. Thus reconciling those who have broken apart or cementing those who are united, he loves concord, delights in concord, enjoys concord, speaks things that create concord.
Abusive speech is anything that for whatever reason -- objective or subjective -- hurts people's feelings and angers them:
Abandoning abusive speech, he abstains from abusive speech. He speaks words that are soothing to the ear, that are affectionate, that go to the heart, that are polite, appealing & pleasing to people at large.
What you are basically saying, is that you would like to engage into divisive and abusive speech, contrary to Buddha's recommendation, because you think that as per the Honeyball Sutta "a true Buddhist" should be absolutely open-minded and unattached -- and therefore not to perceive any speech as divisive/abusive, should easily tolerate a wide range of topics and tones.
This may be so, especially for more advanced practitioners. However, the reason Buddha recommended avoiding speech that may be subjectively perceived as divisive/abusive is because it objectively leads to schisms, arguments, conflicts, and suffering - because most people (including "true Buddhists") are NOT enlightened Buddhas YET and their brains work in certain ways.
Do you understand? It is not enough for you to be objectively right. In order to work with real people you need to understand their subjective biases, weaknesses, hot buttons - and be able to work with them, not against them. To be objectively right while ignoring the objectively existing factors (people's subjective biases) is to be objectively wrong. This is known as to be attached to an abstract idea while ignoring the situation on the field.
