Dear Joanna,

This is a common question; it's even in our searchable knowledge base:

https://www.AskACatholic.com/SiteSearch

There are a lot of quick answers there, so give it a try.

I searched the knowledge base for you and found these web postings that should answer your question:

• Is buying at places who support and possibly fund Planned Parenthood a grave sin?
• What moral culpability do we have with companies that use immoral means to sell their products?
• Am I far enough removed from this action not to be seen as guilty of sin or contributing to evil?
  

I hope this helps,

Mike
