Sadly, we live in a culture where understanding of a topic is no longer a prerequisite for having and announcing an opinion.
There are areas where the right answer is down to personal taste, and where everyone's opinion is of equal merit, but in a deeply technical subject such as this one, expressing an opinion without an understanding of EM emissions and immunity, electronics and avionics systems is simply wrong and it genuinely surprises me how many people feel that ignorance of these areas doesn't limit the value of their opinions.
