First, I don't see any mockery made of these laws as presented. Rather, there is an earnest attempt to explain some of these apparently "odd" (to our modern sensibilities) religious laws. (I agree, it would be good to read an explanation of Deut. 25:11.)
Second, there are modern English translations of the OT and NT. Try _The Message_, which is a recent modern translation in contemporary English.
Third, regarding Christians and their lack of observance of these Jewish laws, I point the reader to the Epistle to the Galatians. That letter deals precisely with that topic. Also, there's a portion of Acts (Acts 15) that states the requirements of the law are not to be expected from Gentile believers.
