How will islam dominate the world

First he explains why the West won’t embrace Islam:

Why would the disbelievers and hypocrites hate for Islam
to be implemented? Simply because they do not wish for their corruption,
evil, crime, cheating, oppression, dishonesty, fraud, lies, tyranny,
freedom, and deception to come to an end, and for justice (Islam) to
prevail.

Did you catch that? Yes he said the West does not want FREEDOM TO COME TO AN END. There is no freedom in Islam. What a wonderful and desirable religion.
He then explains the 3 ways that Islam can dominate the world:

Therefore there are three main ways in which a state or country can become Daar ul-Islam (the domain of Islam):

1. The majority of its citizens embrace Islam and implement the Sharee’ah on their own accord
   
2. A group of Muslims rise, overthrow the government and implement the Sharee’ah by force (coup)
   
3. The Islamic state carries out Jihad as its foreign policy and removes the government
   

“Rule by what Allah has revealed (the Qur’aan and Sunnah) and
do not follow their vain desires, but be aware of them lest they turn
you far away from some of that which Allah has sent down to you…” (EMQ al-Maa-idah, 5: 49)
If they refuse to accept Islam, demand from them the Jizyah
(tax). If they agree to pay, accept it from them and hold off your
hands. If they refuse to pay the tax, seek Allah’s help and fight them…” (Saheeh Muslim #1731)

He then concludes with explaining how Islam will eventually dominate America and Britain.

So
how will Islam dominate the world? Most likely by force! If the people
do not embrace Islam and implement the Sharee’ah on their own accord, it
becomes an obligation upon the Muslims to fight and implement Islam. In
countries such as Britain and America, their people have clearly
rejected to embrace Islam and will never choose to live by the
Sharee’ah.

Therefore,
the only two ways in which these countries can become under the domain
of Islam is by the last two options, a group of Muslims rise and
overthrow the government, or an Islamic state is established elsewhere
and comes to conquer these nations.

Is there any doubt of the threat we face? Or is this just some random radical who misrepresents Islam?

Did you catch that? Yes he said the West does not want FREEDOM TO COME TO AN END. There is no freedom in Islam.
