Humanity in buddhist context is compassion, truth itself is compassion [as it is justice in itself], but truth is also cruel [thus inhuman] and inhereinly hostile to those who entertain falsehood for whatever reason [including the pretext of humanity].
Brotherhood/sisterhood is similar to "mutual stroking", an act which has nothing motivated by truth, but is more motivated by prejudice and personal agenda, such as someone whose view is apparently false, therefore weak, is in need of supporters, therefore he / she is motivated by this desire, thus appeared to be very kind and friendly, even supportive of others' wrong doing and false views.
I view buddhist newsgroup such as alt.talk.religion.buddhism as a filtering mechanism for buddhists, I once comment that the place which is like hell [which is full of trolls and abusers] is the best testing ground for practitioners to prove their competence in dharma.
As buddhist practitioner, mean that we will be rational as opposed to being emotional, years of participating the buddhist newsgroup enable me to exercise rational approach to everything, when I advised others with good advice, I'm in fact advising myself too, its a mutual benefit situation.
Then later when I immerged with hardship and obstacles of life, including divorce and separation from beloved daughter, I feel no less emotional pain, but when I recall my past buddhist activities in the newsgroup, as someone strong and rational, the habit easily recalled, and I can easily free my attachments to the painful past.
So nothing wrong being rational and "inhuman", because this habit will help you one day, when you needed to be strong on your own.
