Views on Casteism in Punjab

This post is in reference to a recent post in this sub in which asked what people would like to remove from Punjab. I noticed that many wrote Casteism. I am originally from Doaba Punjab but have stayed out of Punjab all my life. In regards to some user's concern regarding Casteism in Punjab, I'd like to hear your opinions regarding: 1. Forms of Casteism in Punjab and its extent as it exists in the present 2. Reasons as to why it still exists 3. Status of anti-caste movements and Inter-caste marriages 4. Is a Casteless society possible in Punjab in the future if we walk on the paths that we are currently walking on? 5. What is the solution to the problem of Casteism? You may give your opinion on any or all of the above questions. I'd appreciate it.
