why downvoted in this question?

Anyone have an idea Why I was downvoted in this question? I really don't know.

How can I prove $\pi_1(M)=\pi_1(M-\{q\})$?

Thanks

• Seems I can't cancel that close vote - sorry about that, I was lost and thought I was on main. Only realised when it didn't give me a migrate option. – mdp Nov 27 '12 at 12:00
• @MattPressland why I was downvoted? just to know – user42912 Nov 27 '12 at 12:03
• There is rarely anything to be gained in pursuing reasons for downvoting. See the "Related" questions along the right side of this page --- some of them refer to downvoting behavior. – Gerry Myerson Nov 27 '12 at 12:09
• @GerryMyerson sorry, but I disagree because knowing the reason for downvoting helps us to improve our questions and answers – user42912 Nov 27 '12 at 12:14
• @Rafael That wasn't me, so I can't say. Mine was an unintended vote to close because I got confused and thought you'd posted on the main site, so I was trying to get the question migrated to meta. – mdp Nov 27 '12 at 13:18
• With 2 down votes and 7 up votes, I say: don't worry about the down votes. – GEdgar Nov 27 '12 at 18:28
• Rafael, let me expand: there is rarely anything to be gained in pursuing reasons for downvoting because (among other things) it hardly ever results in knowing the reason for downvoting. And even that is assuming a fact not in evidence, namely, that there actually was a reason for downvoting. – Gerry Myerson Nov 27 '12 at 22:09
• @GerryMyerson yes I understand, thank you :) – user42912 Nov 27 '12 at 23:52
