Depending on where you are, secularism could mean pluralism, no state religion, laicite, or outright state atheism Pluralism is a country like India, there is no state religion, but there are laws regarding religion, such as Hindu joint marriage laws, or Sharia family law; the state picks no state religion, but in practice supports religions. You also have more minor versions like historical Canada, where there were supports for both Protestantism and Catholicism, to the point of government funded Protestant and Catholic schools (Ontario still has 100% government funded Catholic schools). No state religion, like the US, where the state has no established religion, but religion is free to participate in it, including politically. Laicite is France and Quebec, where religion is tolerated, they aren't shutting down organized religion, but don't try to bring religion into politics. State atheism is something like the USSR where the state not only has no religion, but is actively persecuting religion.
