I do agree with you that the article leans a little right in the end, but I feel only to an allowable extent.
I do not agree with you on the statement that Muslims should be allowed to be governed under Sharia on civil matters. What is every religion starts demanding such privileges (which goes unheard by GoI)? Why do we need a Hindu marriages Act 1956 and why did we stop using the tradional laws that we were using till then?
Again, Uniform Civil Code is an extremely difficult task to achieve in India. Brit tried it twice, once in 1828 and 1858 (durin the first and second law commissions) and left it. They could only bring a uniform penal law (IPC 1872). POst Independance also we tried our best and left it to god by putting it in the wish list by mentioning it only in the directive principles of state policy (Art 44).
BJP whose poll manifestos always talk about UCC has not even moved an inch towards this. This requires a lot guts, which I dont think today's politicians have.
