George,
There will often be situations where members disagree on the technicalities of a question. We would nevertheless ask that you always treat others with respect. Contradiction is something that is to be avoided, especially without providing a lot stronger evidence than an apparently simple difference of opinion.
If you do have an alternative option, then presenting it here is always acceptable (much more so than a link elsewhere). If there are known problems with any solution you provide, they can be highlighted, but with respect. We all benefit from clearer understanding. This is never achieved by bad manners or simple contradiction.
Please bear this in mind in future.
