<p>No one is angry or upset with you.  At least, not that I know of.  But Stack Exchange sites do have certain rules that you must abide by, if you wish to participate in this community.  One of those rules is: do not cross-post on multiple Stack Exchange sites.  You may refer to <a href="https://meta.stackexchange.com/q/64068">Is cross-posting a question on multiple Stack Exchange sites permitted if the question is on-topic for each site?</a> for documentation of the policy and explanation of why the policy exists.</p>

<p>The rules exist for a reason: they were chosen in a deliberate attempt to maintain high quality standards and make these sites work well.  It's not that we've never thought of the arguments you raise; we have given this some thought.  We do understand the arguments you raise about why you wish cross-posting was allowed, but there are other reasons why allowing cross-posting would be harmful, and the site has judged that the potential harms outweigh the benefits.  I do hope you'll respect that judgement.</p>

<p>You shouldn't take it personally.  The rules must be enforced-- but no one is trying to single you out or make you feel unwelcome.  Now that you understand the rules, I hope you will continue contributing to Stack Exchange sites in the future, with this in mind.</p>
