With the general public convinced that the Armenians are no good for the country and plan to damage and destory it, there was no opposition to strip them of their rights, instead, there was a big support for such actions.
In order to take away everything from the Armenians when it came to possessions and wealth, as well as destroying their businesses, and stripping them of their human rights, the government planned to weaken the Armenian population. Once the population was poor, hungry, without any institutional rights, they were going to be an easy target, both for the angry Turkish public and the Turkish military.
