It is dishonest to claim that the struggle is against Sisi, that the removal of Sisi will move Egypt towards freedom and justice. No one can afford to be that naive.
Brutal repression is a key institutional function of subordinate regional managers in the global corporate feudal system . If Sisi was not sufficiently brutal, he would be replaced by someone more capable.
He exists exclusively by and for his international owners. If you overthrow him but not his masters, you will not have improved your condition , nor changed the ruling system.
