Why is it that non Kshatriya Hindus always need protection ?

The importance of the role of a Kshatriya in Hindu tradition must be understood by all hindus and non-hindus alike.

It is a solution to the problem that is faced by every ascetic tradition that considers asceticism, non-violence, kshama and daya as the core of its spirituality because once these values are considered supreme then it's practitioners become easy targets for violence, plunder and slavery by external aggressors.

Unlik Mohammadism , hindus came up with a division of labour where the armed combatants and un-armed civilians are differentiated. The civilans are NOT prescribed to indulge in violent behaviour or carry arms and by doing so the 'civilian' and 'softer /spiritual' core of hindusim is protected from external attacks and having to take up violence.

Hinduism came up with the perfect solution to protect it's acetic and non-vilent CORE by having an armed group that aims at protecting the other un-armed and non-violent group who practice non-violence and asceticism.

For example, Shri Rama suo moto fought with the Rakshasas who were killing the non-violent rishis and Munis in the various forests and kept secure the aceticism and spiritual practitioners intact.

Mohammadism on the contrary makes no distinction and prescribed violent behavior for every member and hence the seepage of violence in every aspect of Islam.
