1000% have to agree with the second part of your post. Your relationship with God is a personal affair.
You need not publicise it or broadcast it. Besides, as Muslims we know the status of Prophet Mohammed (PBUH) - so what some random says on the internet is meaningless.
It reminds me of the ordeal of the Prophet at Taif and the words of the Angel of the Mountain...
When the prophet lost his uncle and his wife and was evicted from Makkah, he sought to speak to the people of taif and bring them the message.
The people of taif being rebellious mocked him and set the street urchins join him asking them to stone him and chase him out of the town.
The children pelted you with so many stones that your sandals were caked in your blood, and you looked up to the sky and with one arm shielding your face and one at extended you said " have I done something to upset you lord? So long as you are happy with me, I'm happy".
Upon this Allah (SWT) sent down his reply to Prophet Mohammed (PBUH) in steps.
Step 1: he sent down the Angel of the mountain - who said to the prophet "oh Mohammed do not despair, your lord has heard you and dispatched me, command me, if you command me I will lift up that mountain and crush them (people of taif) under the mountain, I will smite them with the mountain. To which the prophet asked for the locals to be forgiven.
Explanation: Allah's message here was to show the prophet how close he is to God and that he never walks alone.
Step 2: all the people who embraced Islam were slaves, women, elderly people and very few people of influence, whenever the prophet Mohammed (PBUH) would ask people to embrace Islam they would mock him.
So to answer this Allah (SWT) sent to the prophet outside Taif the kings of Jinn, who said " these are words we haven't heard since the time of Moses" and on the spot the kings of Jinn embraced Islam and in turn their entire clans embraced Islam.
Explanation: (Allah's message to the prophet here was if no man will accept your message, if no animal will accept your message, if no creature on earth will accept your message, then I will invent an entity to accept your message because you are Mohammed my prophet and I am ALLAH).
Step 3: To the prophet Mohammed Makkah was like his twin and his connection to it was more than the connection we have with our hometown. His uncle and protector had died, as had his wife and he had no well wisher left in Makkah and had been evicted by the Qureish.
A local warlord of Makkah who was a non-believer and had 12 sons, invited the prophet to return to Makkah under his protection and in the square of Makkah the warlord announced " this man is under my protection and the protection of my twelve sons and if woman wants to know the pain of being a widow or losing a son, let their family try and touch this man".
Explanation: in this Allah showed the prophet that despite him (metaphorically) losing his arms and legs (his wife and uncle) - Allah sent forth for him protectors and well wishers from outside him own circle for God is able to do all things.
This is the status of Prophet Mohammed (PBUH). Does anyone honestly think that some retard on YouTube can tarnish his prestige and magnificence?
