Perhaps we have different views of what forced conversions are. To me, being given a choice of converting or leaving is coercion (it isn't a kind invitation to believe in Christianity - but a forced conversion). The later atrocities to those who chose to convert (atrocities done in the name of Christianity) are indeed to be denounced.
Could shafique please share his thoughts on another type of forced expulsion - the forced removal of the Jews in Khaybar and the Christians in the Najran desert because they were unbelievers and did not convert to Islam?
Without question, this would be a forced conversion, then, since the Jews and Christians would have been allowed to stay in the homes they lived in if they had converted to Islam.
Yahya related to me from Malik from Isma’il bin Abi Hakim that he heard ‘Umar bin ‘Abdul ‘Aziz say, “One of the last things that the Rasoolullaah sallaahu alaihi wa sallam said was, ‘May Allaah fight the Jews and the Christians. They took the graves of their Prophets as places of prostration. Two deens shall not coexist in the land of the Arabs.’”
Yahya related to me from Malik from bin Shihab that the Rasoolulllaah sallaahu alaihi wa sallam said, “Two deens shall not coexist in the Arabian Peninsula.”
Malik said that bin Shihab said, ”’Umar bin al-Khatab searched for information about that until he was absolutely convinced that the Rasoolullaah sallaahu alaihi wa sallam had said, ‘Two deens shall not coexist in the Arabian Peninsula,’ and he therefore expelled the Jews from Khaybar.”
Malik said “That (Arabian Peninsula) is Makkah, Medinah, Yemen and the land of the Arabs.”

and some more hadith:
Narrated Said bin Jubair: Ibn 'Abbas said, "Thursday! What (great thing) took place on Thursday!" Then he started weeping till his tears wetted the gravels of the ground . Then he said, "On Thursday the illness of Allah's Apostle was aggravated and he said, "Fetch me writing materials so that I may have something written to you after which you will never go astray." The people (present there) differed in this matter and people should not differ before a prophet. They said, "Allah's Apostle is seriously sick.' The Prophet said, "Let me alone, as the state in which I am now, is better than what you are calling me for." The Prophet on his death-bed, gave three orders saying, "Expel the pagans from the Arabian Peninsula, respect and give gifts to the foreign delegates as you have seen me dealing with them." I forgot the third (order)" (Ya'qub bin Muhammad said, "I asked Al-Mughira bin 'Abdur-Rahman about the Arabian Peninsula and he said, 'It comprises Mecca, Medina, Al-Yama-ma and Yemen." Ya'qub added, "And Al-Arj, the beginning of Tihama.") - Sahih Bukhari, Volume 4, Book 52, Number 288
Yahya related to me from Malik from Ismail ibn Abi Hakim that he heard Umar ibn Abd al-Aziz say, "One of the last things that the Messenger of Allah, may Allah bless him and grant him peace, said was, 'May Allah fight the jews and the christians.

So, Muhammad and Umar not only indulged in ethnic cleansing, but Umar would have been guilty of forced conversions because he 'coerced' the non-Muslim inhabitants of the hijaz and najran to convert to Islam or leaving their homes and lands they owned.
