It depends entirely on which groups of Muslims the questioner is talking about.
Probably the most prominent, if unfortunately so, Muslim groups are paramilitary and terrorist organizations such as al-Qaeda, Hezbollah, ISIL, Hamas, Taliban etc. Most of these groups are fighting to establish Islamist States in certain areas of the world (usually including areas that overlap between different countries).
There are also numerous Muslim organizations, especially in the US and Europe where Muslims have much greater freedoms to organize politically than they do in the Islamic World. Some of the more famous North American Islamic Groups, which typically try to fight for Muslim Rights include: ISNA, ICNA, CAIR, etc. Other groups include AIFD and Moral Courage, which take a more critical lens to Islamic practice and politics and are fighting to promote a liberalization in the Islamic communities.
There are also several varieties of Muslim militias and armies such as the Shiite militias being organized in Iraq, the Free Syrian Army, and numerous national armies of different Muslim states which were primarily coordinated for self-defense of a particular ethnic group or national group.
It is not the case. In some Muslim countries, the government may be opposed by people for not following democracy or for not responding to people rights in a good life. In some other countries, there may be terrorist groups that are fighting against the government for other personal goals.
No, the Muslim Extremists have not declared war on the Neo-Nazi Groups.
No. Neither of them are fighting "the Muslims" as a group. Most Palestinians are Muslims anyway. The Israeli-Palestinian Conflict is between two national groups: Israelis who are primarily Jewish against Palestinians who are primarily Muslim. However, neither Israeli nor Palestinian forces have declared that they are fighting Islam. There are numerous mosques in both countries where Muslim worshipers freely pray to God.
Fighting between Gupta nobles allowed Muslim forces to successfully conquer parts of India.

In Muslim groups, social groups were often based on kinship, with family ties playing a significant role in shaping social relationships. In addition, social status and wealth also influenced social groupings within Muslim communities. Religious affiliation and piety were also important factors in determining social groups.
