Yes, I believe secularism causes social evils because I dont think the principle of seperating government institutions from religious institutions. I think those with different believes should be able to mend and stick together and not be seperated and I dont think those with different religious believes should be excluded.
Secularism is a way of looking at life that does not take religion, or perhaps even spirituality, into account. Many moral, good people have a secular view of life. Being religious does not make one moral (witness the crusades) and being secular does not make one immoral. An ethical stance helps with social evils.
