There are a few scenarios where you may wish to hide a specific blog topic from appearing in your posts, such as hiding blogs tagged as "featured" from your blog listings.
You can do this by using a condition that checks the topic name, like this:
{% raw %}{% for content in contents %}
{% for topic in content.topic_list %}
{% if topic.name != 'The Topic To Be Excluded' %}
{# Add the markup for the rest of your posts here #}
{% endif %}
{% endfor %}
{% endfor %}
