I'm fortunate enough that I can say that I chose my parents wisely. I respect the diversity and plurality of ideas, appreciate logical approach and always dare to disagree with superficial and shallow arguments. But, I never use abusive language in any discourse. But, it's also the fact that sometimes I'm badly misunderstood. This means that I'm not a good communicator.
"That is not what I meant at all.

That is not it, at all. (Eliot)

With all humility I want to say that some of my friends miserably lack the organic symbiosis between what they say and how they say. For the expression of disagreement, they cross all the limits. My ideal is Voltaire in the context of freedom of speech and expression. He aptly says, "I may disagree with everything that you say, but I'll defend to the last drop of my blood, your right to say so." Despite the inherent partial attitude and systemic irregularities and discrepancies, I endeavour to change the mindset of people who are in the habit of reinforcing the pre-existing system and maintaining status quo.

"I'm not here to fix blame for the past. I'm here to fix the course for the future."
- John F. Kennedy

But the problem with some of my friends (I don't know whether they are worthy of being called friend or not) is that they want to be famous overnight without perseverance and magnanimity.
बड़ी आसानी से मशहूर किया है ख़ुद को
मैंने अपने से बड़े शख़्स को गाली दी है।
- अशर
अपनी एड़ी पर ही चलो खड़े हो जाओ
मुझसे कुछ देर को होते हो बड़े, हो जाओ।
- प्रो. बरेलवी

It's advisable in the classical text :
परोक्षे कार्यहन्तारं, प्रत्यक्षे प्रियवादिनं।
वर्जयेतादृशं मित्रं, विषकुम्भं पयोमुखं।।
And, gradually I'm learning this art.
